NAME
cmakemodules - Reference of available CMake modules.

DESCRIPTION
The "cmake" executable is the CMake command-line interface. It may be
used to configure projects in scripts. Project configuration settings
may be specified on the command line with the -D option. The -i option
will cause cmake to interactively prompt for such settings.

CMake is a cross-platform build system generator. Projects specify
their build process with platform-independent CMake listfiles included
in each directory of a source tree with the name CMakeLists.txt. Users
build a project by using CMake to generate a build system for a native
tool on their platform.

MODULES
The following modules are provided with CMake. They can be used with
INCLUDE(ModuleName).

CMake Modules - Modules coming with CMake, the Cross-Platform Makefile Generator.

This is the documentation for the modules and scripts coming with
CMake. Using these modules you can check the computer system for
installed software packages, features of the compiler and the existance
of headers to name just a few.

AddFileDependencies
ADD_FILE_DEPENDENCIES(source_file depend_files...)

Adds the given files as dependencies to source_file

BundleUtilities

BundleUtilities.cmake

A collection of CMake utility functions useful for dealing with
.app bundles on the Mac and bundle-like directories on any OS.

The following functions are provided by this script:

get_bundle_main_executable
get_dotapp_dir
get_bundle_and_executable
get_bundle_all_executables
get_item_key
clear_bundle_keys
set_bundle_key_values
get_bundle_keys
copy_resolved_item_into_bundle
fixup_bundle_item
fixup_bundle
copy_and_fixup_bundle
verify_bundle_prerequisites
verify_bundle_symlinks
verify_app

Requires CMake 2.6 or greater because it uses function, break
and PARENT_SCOPE. Also depends on GetPrerequisites.cmake.

CMakeBackwardCompatibilityCXX
define a bunch of backwards compatibility variables

CMAKE_ANSI_CXXFLAGS - flag for ansi c++
CMAKE_HAS_ANSI_STRING_STREAM - has <strstream>
INCLUDE(TestForANSIStreamHeaders)
INCLUDE(CheckIncludeFileCXX)
INCLUDE(TestForSTDNamespace)
INCLUDE(TestForANSIForScope)

CMakeDependentOption
Macro to provide an option dependent on other options.

This macro presents an option to the user only if a set of other
conditions are true. When the option is not presented a default
value is used, but any value set by the user is preserved for
when the option is presented again. Example invocation:

CMAKE_DEPENDENT_OPTION(USE_FOO "Use Foo" ON
"USE_BAR;NOT USE_ZOT" OFF)

If USE_BAR is true and USE_ZOT is false, this provides an option
called USE_FOO that defaults to ON. Otherwise, it sets USE_FOO
to OFF. If the status of USE_BAR or USE_ZOT ever changes, any
value for the USE_FOO option is saved so that when the option is
re-enabled it retains its old value.

CMakeDetermineVSServicePack
Includes a public function for assisting users in trying to
determine the

Visual Studio service pack in use.

Sets the passed in variable to one of the following values or an
empty string if unknown.

vc80
vc80sp1
vc90
vc90sp1

Usage: ===========================

if(MSVC)
include(CMakeDetermineVSServicePack)
DetermineVSServicePack( my_service_pack )

if( my_service_pack )
message(STATUS "Detected: ${my_service_pack}")
endif()
endif()

===========================

CMakeFindFrameworks
helper module to find OSX frameworks

CMakeForceCompiler

This module defines macros intended for use by cross-compiling
toolchain files when CMake is not able to automatically detect
the compiler identification.

Macro CMAKE_FORCE_C_COMPILER has the following signature:

CMAKE_FORCE_C_COMPILER(<compiler> <compiler-id>)

It sets CMAKE_C_COMPILER to the given compiler and the cmake
internal variable CMAKE_C_COMPILER_ID to the given compiler-id.
It also bypasses the check for working compiler and basic com‐
piler information tests.

Macro CMAKE_FORCE_CXX_COMPILER has the following signature:

CMAKE_FORCE_CXX_COMPILER(<compiler> <compiler-id>)

It sets CMAKE_CXX_COMPILER to the given compiler and the cmake
internal variable CMAKE_CXX_COMPILER_ID to the given com‐
piler-id. It also bypasses the check for working compiler and
basic compiler information tests.

Macro CMAKE_FORCE_Fortran_COMPILER has the following signature:

CMAKE_FORCE_Fortran_COMPILER(<compiler> <compiler-id>)

It sets CMAKE_Fortran_COMPILER to the given compiler and the
cmake internal variable CMAKE_Fortran_COMPILER_ID to the given
compiler-id. It also bypasses the check for working compiler and
basic compiler information tests.

So a simple toolchain file could look like this:

INCLUDE (CMakeForceCompiler)
SET(CMAKE_SYSTEM_NAME Generic)
CMAKE_FORCE_C_COMPILER (chc12 MetrowerksHicross)
CMAKE_FORCE_CXX_COMPILER (chc12 MetrowerksHicross)

CMakePrintSystemInformation
print system information

This file can be used for diagnostic purposes just include it in
a project to see various internal CMake variables.

CMakeVerifyManifest

CMakeVerifyManifest.cmake

This script is used to verify that embeded manifests and side by
side manifests for a project match. To run this script, cd to a
directory and run the script with cmake -P. On the command line
you can pass in versions that are OK even if not found in the
.manifest files. For example, cmake -Dallow_ver‐
sions=8.0.50608.0 -PCmakeVerifyManifest.cmake could be used to
allow an embeded manifest of 8.0.50608.0 to be used in a project
even if that version was not found in the .manifest file.

CPack Build binary and source package installers

The CPack module generates binary and source installers in a
variety of formats using the cpack program. Inclusion of the
CPack module adds two new targets to the resulting makefiles,
package and package_source, which build the binary and source
installers, respectively. The generated binary installers con‐
tain everything installed via CMake's INSTALL command (and the
deprecated INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS
commands).

For certain kinds of binary installers (including the graphical
installers on Mac OS X and Windows), CPack generates installers
that allow users to select individual application components to
install. The contents of each of the components are identified
by the COMPONENT argument of CMake's INSTALL command. These com‐
ponents can be annotated with user-friendly names and descrip‐
tions, inter-component dependencies, etc., and grouped in vari‐
ous ways to customize the resulting installer. See the
cpack_add_* commands, described below, for more information
about component-specific installations.

Before including the CPack module, there are a variety of vari‐
ables that can be set to customize the resulting installers. The
most commonly-used variables are:

CPACK_PACKAGE_NAME - The name of the package (or application). If
not specified, defaults to the project name.

CPACK_PACKAGE_VENDOR - The name of the package vendor (e.g.,
"Kitware").

CPACK_PACKAGE_VERSION_MAJOR - Package major Version

CPACK_PACKAGE_VERSION_MINOR - Package minor Version

CPACK_PACKAGE_VERSION_PATCH - Package patch Version

CPACK_PACKAGE_DESCRIPTION_FILE - A text file used to describe the
project. Used, for example, the introduction screen of a
CPack-generated Windows installer to describe the project.

CPACK_PACKAGE_DESCRIPTION_SUMMARY - Short description of the
project (only a few words).

CPACK_PACKAGE_FILE_NAME - The name of the package file to generate,
not including the extension. For example, cmake-2.6.1-Linux-i686.

CPACK_PACKAGE_INSTALL_DIRECTORY - Installation directory on the
target system, e.g., "CMake 2.5".

CPACK_RESOURCE_FILE_LICENSE - License file for the project, which
will typically be displayed to the user (often with an explicit
"Accept" button, for graphical installers) prior to installation.

CPACK_RESOURCE_FILE_README - ReadMe file for the project, which
typically describes in some detail

CPACK_RESOURCE_FILE_WELCOME - Welcome file for the project, which
welcomes users to this installer. Typically used in the graphical
installers on Windows and Mac OS X.

CPACK_MONOLITHIC_INSTALL - Disables the component-based
installation mechanism, so that all components are always installed.

CPACK_GENERATOR - List of CPack generators to use. If not
specified, CPack will create a set of options (e.g.,
CPACK_BINARY_NSIS) allowing the user to enable/disable individual
generators.

CPACK_OUTPUT_CONFIG_FILE - The name of the CPack configuration file
for binary installers that will be generated by the CPack
module. Defaults to CPackConfig.cmake.

CPACK_PACKAGE_EXECUTABLES - Lists each of the executables along
with a text label, to be used to create Start Menu shortcuts on
Windows. For example, setting this to the list ccmake;CMake will
create a shortcut named "CMake" that will execute the installed
executable ccmake.

CPACK_STRIP_FILES - List of files to be stripped. Starting with
CMake 2.6.0 CPACK_STRIP_FILES will be a boolean variable which
enables stripping of all files (a list of files evaluates to TRUE
in CMake, so this change is compatible).

The following CPack variables are specific to source packages,
and will not affect binary packages:

CPACK_SOURCE_PACKAGE_FILE_NAME - The name of the source package,
e.g., cmake-2.6.1

CPACK_SOURCE_STRIP_FILES - List of files in the source tree that
will be stripped. Starting with CMake 2.6.0
CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables
stripping of all files (a list of files evaluates to TRUE in CMake,
so this change is compatible).

CPACK_SOURCE_GENERATOR - List of generators used for the source
packages. As with CPACK_GENERATOR, if this is not specified then
CPack will create a set of options (e.g., CPACK_SOURCE_ZIP)
allowing users to select which packages will be generated.

CPACK_SOURCE_OUTPUT_CONFIG_FILE - The name of the CPack
configuration file for source installers that will be generated by
the CPack module. Defaults to CPackSourceConfig.cmake.

CPACK_SOURCE_IGNORE_FILES - Pattern of files in the source tree
that won't be packaged when building a source package. This is a
list of patterns, e.g., /CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*

The following variables are specific to the DragNDrop installers
built on Mac OS X:

CPACK_DMG_VOLUME_NAME - The volume name of the generated disk
image. Defaults to CPACK_PACKAGE_FILE_NAME.

CPACK_DMG_FORMAT - The disk image format. Common values are UDRO
(UDIF read-only), UDZO (UDIF zlib-compressed) or UDBZ (UDIF
bzip2-compressed). Refer to hdiutil(1) for more information on
other available formats.

CPACK_DMG_DS_STORE - Path to a custom .DS_Store file which e.g.
can be used to specify the Finder window position/geometry and
layout (such as hidden toolbars, placement of the icons etc.).
This file has to be generated by the Finder (either manually or
through OSA-script) using a normal folder from which the .DS_Store
file can then be extracted.

CPACK_DMG_BACKGROUND_IMAGE - Path to an image file which is to be
used as the background for the Finder Window when the disk image
is opened. By default no background image is set. The background
image is applied after applying the custom .DS_Store file.

CPACK_COMMAND_HDIUTIL - Path to the hdiutil(1) command used to
operate on disk image files on Mac OS X. This variable can be used
to override the automatically detected command (or specify its
location if the auto-detection fails to find it.)

CPACK_COMMAND_SETFILE - Path to the SetFile(1) command used to set
extended attributes on files and directories on Mac OS X. This
variable can be used to override the automatically detected
command (or specify its location if the auto-detection fails to
find it.)

CPACK_COMMAND_REZ - Path to the Rez(1) command used to compile
resources on Mac OS X. This variable can be used to override the
automatically detected command (or specify its location if the
auto-detection fails to find it.)

Installers built on Mac OS X using the Bundle generator use the
aforementioned DragNDrop variables, plus the following Bun‐
dle-specific parameters:

CPACK_BUNDLE_NAME - The name of the generated bundle. This
appears in the OSX finder as the bundle name. Required.

CPACK_BUNDLE_PLIST - Path to an OSX plist file that will be used
as the Info.plist for the generated bundle. This assumes that
the caller has generated or specified their own Info.plist file.
Required.

CPACK_BUNDLE_ICON - Path to an OSX icns file that will be used as
the icon for the generated bundle. This is the icon that appears
in the OSX finder for the bundle, and in the OSX dock when the
bundle is opened. Required.

CPACK_BUNDLE_STARTUP_SCRIPT - Path to an executable or script that
will be run whenever an end-user double-clicks the generated bundle
in the OSX Finder. Optional.

The following variables are specific to the graphical installers
built on Windows using the Nullsoft Installation System.

CPACK_PACKAGE_INSTALL_REGISTRY_KEY - Registry key used when
installing this project.

CPACK_NSIS_MUI_ICON - The icon file (.ico) for the generated
install program.

CPACK_NSIS_MUI_UNIICON - The icon file (.ico) for the generated
uninstall program.

CPACK_PACKAGE_ICON - A branding image that will be displayed inside
the installer.

CPACK_NSIS_EXTRA_INSTALL_COMMANDS - Extra NSIS commands that will
be added to the install Section.

CPACK_NSIS_EXTRA_UNINSTALL_COMMANDS - Extra NSIS commands that will
be added to the uninstall Section.

CPACK_NSIS_COMPRESSOR - The arguments that will be passed to the
NSIS SetCompressor command.

CPACK_NSIS_MODIFY_PATH - If this is set to "ON", then an extra page
will appear in the installer that will allow the user to choose
whether the program directory should be added to the system PATH
variable.

CPACK_NSIS_DISPLAY_NAME - The display name string that appears in
the Windows Add/Remove Program control panel

CPACK_NSIS_PACKAGE_NAME - The title displayed at the top of the
installer.

CPACK_NSIS_INSTALLED_ICON_NAME - A path to the executable that
contains the installer icon.

CPACK_NSIS_HELP_LINK - URL to a web site providing assistance in
installing your application.

CPACK_NSIS_URL_INFO_ABOUT - URL to a web site providing more
information about your application.

CPACK_NSIS_CONTACT - Contact information for questions and comments
about the installation process.

CPACK_NSIS_CREATE_ICONS_EXTRA - Additional NSIS commands for
creating start menu shortcuts.

CPACK_NSIS_DELETE_ICONS_EXTRA -Additional NSIS commands to
uninstall start menu shortcuts.

The following variable is specific to installers build on Mac OS
X using PackageMaker:

CPACK_OSX_PACKAGE_VERSION - The version of Mac OS X that the
resulting PackageMaker archive should be compatible
with. Different versions of Mac OS X support different
features. For example, CPack can only build component-based
installers for Mac OS X 10.4 or newer, and can only build
installers that download component son-the-fly for Mac OS X 10.5
or newer. If left blank, this value will be set to the minimum
version of Mac OS X that supports the requested features. Set this
variable to some value (e.g., 10.4) only if you want to guarantee
that your installer will work on that version of Mac OS X, and
don't mind missing extra features available in the installer
shipping with later versions of Mac OS X.

The following variables are for advanced uses of CPack:

CPACK_CMAKE_GENERATOR - What CMake generator should be used if the
project is CMake project. Defaults to the value of CMAKE_GENERATOR;
few users will want to change this setting.

CPACK_INSTALL_CMAKE_PROJECTS - List of four values that specify
what project to install. The four values are: Build directory,
Project Name, Project Component, Directory. If omitted, CPack will
build an installer that installers everything.

CPACK_SYSTEM_NAME - System name, defaults to the value of
${CMAKE_SYSTEM_NAME}.

CPACK_PACKAGE_VERSION - Package full version, used internally. By
default, this is built from CPACK_PACKAGE_VERSION_MAJOR,
CPACK_PACKAGE_VERSION_MINOR, and CPACK_PACKAGE_VERSION_PATCH.

CPACK_TOPLEVEL_TAG - Directory for the installed files.

CPACK_INSTALL_COMMANDS - Extra commands to install components.

CPACK_INSTALL_DIRECTORIES - Extra directories to install.

Component-specific installation allows users to select specific
sets of components to install during the install process.
Installation components are identified by the COMPONENT argument
of CMake's INSTALL commands, and should be further described by
the following CPack commands:

cpack_add_component - Describes a CPack installation component
named by the COMPONENT argument to a CMake INSTALL command.

cpack_add_component(compname
[DISPLAY_NAME name]
[DESCRIPTION description]
[HIDDEN | REQUIRED | DISABLED ]
[GROUP group]
[DEPENDS comp1 comp2 ... ]
[INSTALL_TYPES type1 type2 ... ]
[DOWNLOADED]
[ARCHIVE_FILE filename])

The cmake_add_component command describes an installation
component, which the user can opt to install or remove as part of
the graphical installation process. compname is the name of the
component, as provided to the COMPONENT argument of one or more
CMake INSTALL commands.

DISPLAY_NAME is the displayed name of the component, used in
graphical installers to display the component name. This value can
be any string.

DESCRIPTION is an extended description of the component, used in
graphical installers to give the user additional information about
the component. Descriptions can span multiple lines using "\n" as
the line separator. Typically, these descriptions should be no
more than a few lines long.

HIDDEN indicates that this component will be hidden in the
graphical installer, so that the user cannot directly change
whether it is installed or not.

REQUIRED indicates that this component is required, and therefore
will always be installed. It will be visible in the graphical
installer, but it cannot be unselected. (Typically, required
components are shown greyed out).

DISABLED indicates that this component should be disabled
(unselected) by default. The user is free to select this component
for installation, unless it is also HIDDEN.

DEPENDS lists the components on which this component depends. If
this component is selected, then each of the components listed
must also be selected. The dependency information is encoded
within the installer itself, so that users cannot install
inconsitent sets of components.

GROUP names the component group of which this component is a
part. If not provided, the component will be a standalone
component, not part of any component group. Component groups are
described with the cpack_add_component_group command, detailed
below.

INSTALL_TYPES lists the installation types of which this component
is a part. When one of these installations types is selected, this
component will automatically be selected. Installation types are
described with the cpack_add_install_type command, detailed below.

DOWNLOADED indicates that this component should be downloaded
on-the-fly by the installer, rather than packaged in with the
installer itself. For more information, see the cpack_configure_downloads
command.

ARCHIVE_FILE provides a name for the archive file created by CPack
to be used for downloaded components. If not supplied, CPack will
create a file with some name based on CPACK_PACKAGE_FILE_NAME and
the name of the component. See cpack_configure_downloads for more
information.

cpack_add_component_group - Describes a group of related CPack
installation components.

cpack_add_component_group(groupname
[DISPLAY_NAME name]
[DESCRIPTION description]
[PARENT_GROUP parent]
[EXPANDED]
[BOLD_TITLE])

The cpack_add_component_group describes a group of installation
components, which will be placed together within the listing of
options. Typically, component groups allow the user to
select/deselect all of the components within a single group via a
single group-level option. Use component groups to reduce the
complexity of installers with many options. groupname is an
arbitrary name used to identify the group in the GROUP argument of
the cpack_add_component command, which is used to place a
component in a group. The name of the group must not conflict with
the name of any component.

DISPLAY_NAME is the displayed name of the component group, used in
graphical installers to display the component group name. This
value can be any string.

DESCRIPTION is an extended description of the component group,
used in graphical installers to give the user additional
information about the components within that group. Descriptions
can span multiple lines using "\n" as the line
separator. Typically, these descriptions should be no more than a
few lines long.

PARENT_GROUP, if supplied, names the parent group of this group.
Parent groups are used to establish a hierarchy of groups,
providing an arbitrary hierarchy of groups.

EXPANDED indicates that, by default, the group should show up as
"expanded", so that the user immediately sees all of the
components within the group. Otherwise, the group will initially
show up as a single entry.

BOLD_TITLE indicates that the group title should appear in bold,
to call the user's attention to the group.

cpack_add_install_type - Add a new installation type containing a
set of predefined component selections to the graphical installer.

cpack_add_install_type(typename
[DISPLAY_NAME name])

The cpack_add_install_type command identifies a set of preselected
components that represents a common use case for an
application. For example, a "Developer" install type might include
an application along with its header and library files, while an
"End user" install type might just include the application's
executable. Each component identifies itself with one or more
install types via the INSTALL_TYPES argument to
cpack_add_component.

DISPLAY_NAME is the displayed name of the install type, which will
typically show up in a drop-down box within a graphical
installer. This value can be any string.

cpack_configure_downloads - Configure CPack to download selected
components on-the-fly as part of the installation process.

cpack_configure_downloads(site
[UPLOAD_DIRECTORY dirname]
[ALL]
[ADD_REMOVE|NO_ADD_REMOVE])

The cpack_configure_downloads command configures installation-time
downloads of selected components. For each downloadable component,
CPack will create an archive containing the contents of that
component, which should be uploaded to the given site. When the
user selects that component for installation, the installer will
download and extract the component in place. This feature is
useful for creating small installers that only download the
requested components, saving bandwidth. Additionally, the
installers are small enough that they will be installed as part of
the normal installation process, and the "Change" button in
Windows Add/Remove Programs control panel will allow one to add or
remove parts of the application after the original
installation. On Windows, the downloaded-components functionality
requires the ZipDLL plug-in for NSIS, available at:

http://nsis.sourceforge.net/ZipDLL_plug-in

On Mac OS X, installers that download components on-the-fly can
only be built and installed on system using Mac OS X 10.5 or
later.

The site argument is a URL where the archives for downloadable
components will reside, e.g., http://www.cmake.org/files/2.6.1/installer/
All of the archives produced by CPack should be uploaded to that location.

UPLOAD_DIRECTORY is the local directory where CPack will create the
various archives for each of the components. The contents of this
directory should be uploaded to a location accessible by the URL given
in the site argument. If omitted, CPack will use the directory
CPackUploads inside the CMake binary directory to store the generated
archives.

The ALL flag indicates that all components be downloaded. Otherwise, only
those components explicitly marked as DOWNLOADED or that have a specified
ARCHIVE_FILE will be downloaded. Additionally, the ALL option implies
ADD_REMOVE (unless NO_ADD_REMOVE is specified).

ADD_REMOVE indicates that CPack should install a copy of the installer
that can be called from Windows' Add/Remove Programs dialog (via the
"Modify" button) to change the set of installed components. NO_ADD_REMOVE
turns off this behavior. This option is ignored on Mac OS X.

CTest Configure a project for testing with CTest/CDash

Include this module in the top CMakeLists.txt file of a project
to enable testing with CTest and dashboard submissions to CDash:

project(MyProject)
...
include(CTest)

The module automatically creates a BUILD_TESTING option that
selects whether to enable testing support (ON by default).
After including the module, use code like

if(BUILD_TESTING)
# ... CMake code to create tests ...
endif()

to creating tests when testing is enabled.

To enable submissions to a CDash server, create a CTestCon‐
fig.cmake file at the top of the project with content such as

set(CTEST_PROJECT_NAME "MyProject")
set(CTEST_NIGHTLY_START_TIME "01:00:00 UTC")
set(CTEST_DROP_METHOD "http")
set(CTEST_DROP_SITE "my.cdash.org")
set(CTEST_DROP_LOCATION "/submit.php?project=MyProject")
set(CTEST_DROP_SITE_CDASH TRUE)

(the CDash server can provide the file to a project administra‐
tor who configures 'MyProject'). Settings in the config file are
shared by both this CTest module and the CTest command-line
tool's dashboard script mode (ctest -S).

While building a project for submission to CDash, CTest scans
the build output for errors and warnings and reports them with
surrounding context from the build log. This generic approach
works for all build tools, but does not give details about the
command invocation that produced a given problem. One may get
more detailed reports by adding

set(CTEST_USE_LAUNCHERS 1)

to the CTestConfig.cmake file. When this option is enabled, the
CTest module tells CMake's Makefile generators to invoke every
command in the generated build system through a CTest launcher
program. (Currently the CTEST_USE_LAUNCHERS option is ignored
on non-Makefile generators.) During a manual build each
launcher transparently runs the command it wraps. During a
CTest-driven build for submission to CDash each launcher reports
detailed information when its command fails or warns. (Setting
CTEST_USE_LAUNCHERS in CTestConfig.cmake is convenient, but also
adds the launcher overhead even for manual builds. One may
instead set it in a CTest dashboard script and add it to the
CMake cache for the build tree.)

CTestScriptMode

CHECK_TYPE_SIZE(TYPE VARIABLE [BUILTIN_TYPES_ONLY])

Check if the type exists and determine its size. On return,
"HAVE_${VARIABLE}" holds the existence of the type, and "${VARI‐
ABLE}" holds one of the following:

<size> = type has non-zero size <size>
"0" = type has arch-dependent size (see below)
"" = type does not exist

Furthermore, the variable "${VARIABLE}_CODE" holds C preproces‐
sor code to define the macro "${VARIABLE}" to the size of the
type, or leave the macro undefined if the type does not exist.

The variable "${VARIABLE}" may be "0" when CMAKE_OSX_ARCHITEC‐
TURES has multiple architectures for building OS X universal
binaries. This indicates that the type size varies across archi‐
tectures. In this case "${VARIABLE}_CODE" contains C preproces‐
sor tests mapping from each architecture macro to the corre‐
sponding type size. The list of architecture macros is stored in
"${VARIABLE}_KEYS", and the value for each key is stored in
"${VARIABLE}-${KEY}".

If the BUILTIN_TYPES_ONLY option is not given, the macro checks
for headers <sys/types.h>, <stdint.h>, and <stddef.h>, and saves
results in HAVE_SYS_TYPES_H, HAVE_STDINT_H, and HAVE_STDDEF_H.
The type size check automatically includes the available head‐
ers, thus supporting checks of types defined in the headers.

The following variables may be set before calling this macro to
modify the way the check is run:

CheckVariableExists
Check if the variable exists.

CHECK_VARIABLE_EXISTS(VAR VARIABLE)

VAR - the name of the variable
VARIABLE - variable to store the result

This macro is only for C variables.

The following variables may be set before calling this macro to
modify the way the check is run:

CMAKE_REQUIRED_FLAGS = string of compile command line flags
CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
CMAKE_REQUIRED_LIBRARIES = list of libraries to link

Dart Configure a project for testing with CTest or old Dart Tcl
Client

This file is the backwards-compatibility version of the CTest
module. It supports using the old Dart 1 Tcl client for driving
dashboard submissions as well as testing with CTest. This mod‐
ule should be included in the CMakeLists.txt file at the top of
a project. Typical usage:

INCLUDE(Dart)
IF(BUILD_TESTING)
# ... testing related CMake code ...
ENDIF(BUILD_TESTING)

The BUILD_TESTING option is created by the Dart module to deter‐
mine whether testing support should be enabled. The default is
ON.

Documentation
DocumentationVTK.cmake

This file provides support for the VTK documentation framework.
It relies on several tools (Doxygen, Perl, etc).

ExternalProject
Create custom targets to build projects in external trees

The 'ExternalProject_Add' function creates a custom target to
drive download, update/patch, configure, build, install and test
steps of an external project:

ExternalProject_Add(<name> # Name for custom target
[DEPENDS projects...] # Targets on which the project depends
[PREFIX dir] # Root dir for entire project
[LIST_SEPARATOR sep] # Sep to be replaced by ; in cmd lines
[TMP_DIR dir] # Directory to store temporary files
[STAMP_DIR dir] # Directory to store step timestamps
#--Download step--------------
[DOWNLOAD_DIR dir] # Directory to store downloaded files
[DOWNLOAD_COMMAND cmd...] # Command to download source tree
[CVS_REPOSITORY cvsroot] # CVSROOT of CVS repository
[CVS_MODULE mod] # Module to checkout from CVS repo
[CVS_TAG tag] # Tag to checkout from CVS repo
[SVN_REPOSITORY url] # URL of Subversion repo
[SVN_REVISION rev] # Revision to checkout from Subversion repo
[URL /.../src.tgz] # Full path or URL of source
[TIMEOUT seconds] # Time allowed for file download operations
#--Update/Patch step----------
[UPDATE_COMMAND cmd...] # Source work-tree update command
[PATCH_COMMAND cmd...] # Command to patch downloaded source
#--Configure step-------------
[SOURCE_DIR dir] # Source dir to be used for build
[CONFIGURE_COMMAND cmd...] # Build tree configuration command
[CMAKE_COMMAND /.../cmake] # Specify alternative cmake executable
[CMAKE_GENERATOR gen] # Specify generator for native build
[CMAKE_ARGS args...] # Arguments to CMake command line
#--Build step-----------------
[BINARY_DIR dir] # Specify build dir location
[BUILD_COMMAND cmd...] # Command to drive the native build
[BUILD_IN_SOURCE 1] # Use source dir for build dir
#--Install step---------------
[INSTALL_DIR dir] # Installation prefix
[INSTALL_COMMAND cmd...] # Command to drive install after build
#--Test step---------------
[TEST_BEFORE_INSTALL 1] # Add test step executed before install step
[TEST_AFTER_INSTALL 1] # Add test step executed after install step
[TEST_COMMAND cmd...] # Command to drive test
)

The *_DIR options specify directories for the project, with
default directories computed as follows. If the PREFIX option is
given to ExternalProject_Add() or the EP_PREFIX directory prop‐
erty is set, then an external project is built and installed
under the specified prefix:

TMP_DIR = <prefix>/tmp
STAMP_DIR = <prefix>/src/<name>-stamp
DOWNLOAD_DIR = <prefix>/src
SOURCE_DIR = <prefix>/src/<name>
BINARY_DIR = <prefix>/src/<name>-build
INSTALL_DIR = <prefix>

Otherwise, if the EP_BASE directory property is set then compo‐
nents of an external project are stored under the specified
base:

TMP_DIR = <base>/tmp/<name>
STAMP_DIR = <base>/Stamp/<name>
DOWNLOAD_DIR = <base>/Download/<name>
SOURCE_DIR = <base>/Source/<name>
BINARY_DIR = <base>/Build/<name>
INSTALL_DIR = <base>/Install/<name>

If no PREFIX, EP_PREFIX, or EP_BASE is specified then the
default is to set PREFIX to "<name>-prefix". Relative paths are
interpreted with respect to the build directory corresponding to
the source directory in which ExternalProject_Add is invoked.

If SOURCE_DIR is explicitly set to an existing directory the
project will be built from it. Otherwise a download step must be
specified using one of the DOWNLOAD_COMMAND, CVS_*, SVN_*, or
URL options. The URL option may refer locally to a directory or
source tarball, or refer to a remote tarball (e.g.
http://.../src.tgz).

The 'ExternalProject_Add_Step' function adds a custom step to an
external project:

ExternalProject_Add_Step(<name> <step> # Names of project and custom step
[COMMAND cmd...] # Command line invoked by this step
[COMMENT "text..."] # Text printed when step executes
[DEPENDEES steps...] # Steps on which this step depends
[DEPENDERS steps...] # Steps that depend on this step
[DEPENDS files...] # Files on which this step depends
[ALWAYS 1] # No stamp file, step always runs
[WORKING_DIRECTORY dir] # Working directory for command
)

The command line, comment, and working directory of every stan‐
dard and custom step is processed to replace tokens
<SOURCE_DIR>, <BINARY_DIR>, <INSTALL_DIR>, and <TMP_DIR> with
corresponding property values.

The 'ExternalProject_Get_Property' function retrieves external
project target properties:

ExternalProject_Get_Property(<name> [prop1 [prop2 [...]]])

It stores property values in variables of the same name. Prop‐
erty names correspond to the keyword argument names of 'Exter‐
nalProject_Add'.

FeatureSummary
Macros for generating a summary of enabled/disabled features

PRINT_ENABLED_FEATURES()

Print a summary of all enabled features. By default all successfull
FIND_PACKAGE() calls will appear here, except the ones which used the
QUIET keyword. Additional features can be added by appending an entry
to the global ENABLED_FEATURES property. If SET_FEATURE_INFO() is
used for that feature, the output will be much more informative.

PRINT_DISABLED_FEATURES()

Same as PRINT_ENABLED_FEATURES(), but for disabled features. It can
be extended the same way by adding to the global property
DISABLED_FEATURES.

SET_FEATURE_INFO(NAME DESCRIPTION [URL [COMMENT] ] )

Use this macro to set up information about the named feature, which will
then be displayed by PRINT_ENABLED/DISABLED_FEATURES().
Example: SET_FEATURE_INFO(LibXml2 "XML processing library."
"http://xmlsoft.org/")

FindALSA
Find alsa

Find the alsa libraries (asound)

This module defines the following variables:
ALSA_FOUND - True if ALSA_INCLUDE_DIR & ALSA_LIBRARY are found
ALSA_LIBRARIES - Set when ALSA_LIBRARY is found
ALSA_INCLUDE_DIRS - Set when ALSA_INCLUDE_DIR is found

ALSA_INCLUDE_DIR - where to find asoundlib.h, etc.
ALSA_LIBRARY - the asound library

FindASPELL
Try to find ASPELL

Once done this will define

ASPELL_FOUND - system has ASPELL
ASPELL_INCLUDE_DIR - the ASPELL include directory
ASPELL_LIBRARIES - The libraries needed to use ASPELL
ASPELL_DEFINITIONS - Compiler switches required for using ASPELL

FindAVIFile
Locate AVIFILE library and include paths

AVIFILE (http://avifile.sourceforge.net/)is a set of libraries
for i386 machines to use various AVI codecs. Support is limited
beyond Linux. Windows provides native AVI support, and so
doesn't need this library. This module defines

AVIFILE_INCLUDE_DIR, where to find avifile.h , etc.
AVIFILE_LIBRARIES, the libraries to link against
AVIFILE_DEFINITIONS, definitions to use when compiling
AVIFILE_FOUND, If false, don't try to use AVIFILE

FindBISON
Find bison executable and provides macros to generate custom
build rules

The module defines the following variables:

BISON_EXECUTABLE - path to the bison program
BISON_VERSION - version of bison
BISON_FOUND - true if the program was found

If bison is found, the module defines the macros:

BISON_TARGET(<Name> <YaccInput> <CodeOutput> [VERBOSE <file>]
[COMPILE_FLAGS <string>])

which will create a custom rule to generate a parser. <YaccIn‐
put> is the path to a yacc file. <CodeOutput> is the name of
the source file generated by bison. A header file is also be
generated, and contains the token list. If COMPILE_FLAGS
option is specified, the next parameter is added in the
bison command line. if VERBOSE option is specified, <file> is
created and contains verbose descriptions of the grammar and
parser. The macro defines a set of variables:

BISON_${Name}_DEFINED - true is the macro ran successfully
BISON_${Name}_INPUT - The input source file, an alias for <YaccInput>
BISON_${Name}_OUTPUT_SOURCE - The source file generated by bison
BISON_${Name}_OUTPUT_HEADER - The header file generated by bison
BISON_${Name}_OUTPUTS - The sources files generated by bison
BISON_${Name}_COMPILE_FLAGS - Options used in the bison command line

====================================================================
Example:

find_package(BISON)
BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp)
add_executable(Foo main.cpp ${BISON_MyParser_OUTPUTS})
====================================================================

FindBLAS
Find BLAS library

This module finds an installed fortran library that implements
the BLAS linear-algebra interface (see
http://www.netlib.org/blas/). The list of libraries searched for
is taken from the autoconf macro file, acx_blas.m4 (distributed
at http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).

This module sets the following variables:

BLAS_FOUND - set to true if a library implementing the BLAS interface
is found
BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l
and -L).
BLAS_LIBRARIES - uncached list of libraries (using full path name) to
link against to use BLAS
BLAS95_LIBRARIES - uncached list of libraries (using full path name)
to link against to use BLAS95 interface
BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface
is found
BLA_STATIC if set on this determines what kind of linkage we do (static)
BLA_VENDOR if set checks only the specified vendor, if not set checks
all the possibilities
BLA_F95 if set on tries to find the f95 interfaces for BLAS/LAPACK

######### ## List of vendors (BLA_VENDOR) valid in this module #
ATLAS, PhiPACK,CXML,DXML,SunPerf,SCSL,SGIMATH,IBMESSL,Intel10_32
(intel mkl v10 32 bit),Intel10_64lp (intel mkl v10 64 bit,lp
thread model, lp64 model), # Intel( older versions of mkl 32
and 64 bit), ACML,Apple, NAS, Generic C/CXX should be enabled to
use Intel mkl

FindBZip2
Try to find BZip2

Once done this will define

BZIP2_FOUND - system has BZip2
BZIP2_INCLUDE_DIR - the BZip2 include directory
BZIP2_LIBRARIES - Link these to use BZip2
BZIP2_DEFINITIONS - Compiler switches required for using BZip2
BZIP2_NEED_PREFIX - this is set if the functions are prefixed with BZ2_

FindBoost
Try to find Boost include dirs and libraries

Usage of this module as follows:

NOTE: Take note of the Boost_ADDITIONAL_VERSIONS variable below.
Due to Boost naming conventions and limitations in CMake this
find module is NOT future safe with respect to Boost version
numbers, and may break.

== Using Header-Only libraries from within Boost: ==

find_package( Boost 1.36.0 )
if(Boost_FOUND)
include_directories(${Boost_INCLUDE_DIRS})
add_executable(foo foo.cc)
endif()

== Using actual libraries from within Boost: ==

set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)
find_package( Boost 1.36.0 COMPONENTS date_time filesystem system ... )

if(Boost_FOUND)
include_directories(${Boost_INCLUDE_DIRS})
add_executable(foo foo.cc)
target_link_libraries(foo ${Boost_LIBRARIES})
endif()

The components list needs to contain actual names of boost
libraries only, such as "date_time" for "libboost_date_time".
If you're using parts of Boost that contain header files only
(e.g. foreach) you do not need to specify COMPONENTS.

You should provide a minimum version number that should be used.
If you provide this version number and specify the REQUIRED
attribute, this module will fail if it can't find the specified
or a later version. If you specify a version number this is
automatically put into the considered list of version numbers
and thus doesn't need to be specified in the Boost_ADDI‐
TIONAL_VERSIONS variable (see below).

NOTE for Visual Studio Users:

Automatic linking is used on MSVC & Borland compilers by default when
#including things in Boost. It's important to note that setting
Boost_USE_STATIC_LIBS to OFF is NOT enough to get you dynamic linking,
should you need this feature. Automatic linking typically uses static
libraries with a few exceptions (Boost.Python is one).

Please see the section below near Boost_LIB_DIAGNOSTIC_DEFINITIONS for
more details. Adding a TARGET_LINK_LIBRARIES() as shown in the example
above appears to cause VS to link dynamically if Boost_USE_STATIC_LIBS
gets set to OFF. It is suggested you avoid automatic linking since it
will make your application less portable.

=========== The mess that is Boost_ADDITIONAL_VERSIONS (sorry?)
============

OK, so the Boost_ADDITIONAL_VERSIONS variable can be used to
specify a list of boost version numbers that should be taken
into account when searching for Boost. Unfortunately boost puts
the version number into the actual filename for the libraries,
so this variable will certainly be needed in the future when new
Boost versions are released.

Currently this module searches for the following version num‐
bers: 1.33, 1.33.0, 1.33.1, 1.34, 1.34.0, 1.34.1, 1.35, 1.35.0,
1.35.1, 1.36, 1.36.0, 1.36.1, 1.37, 1.37.0, 1.38, 1.38.0, 1.39,
1.39.0, 1.40, 1.40.0, 1.41, 1.41.0

NOTE: If you add a new major 1.x version in Boost_ADDI‐
TIONAL_VERSIONS you should add both 1.x and 1.x.0 as shown
above. Official Boost include directories omit the 3rd version
number from include paths if it is 0 although not all binary
Boost releases do so.

SET(Boost_ADDITIONAL_VERSIONS "1.78" "1.78.0" "1.79" "1.79.0")

===================================== =============
========================

Variables used by this module, they can change the default be‐
haviour and need to be set before calling find_package:

Boost_USE_MULTITHREADED Can be set to OFF to use the non-multithreaded
boost libraries. If not specified, defaults
to ON.

Boost_USE_STATIC_LIBS Can be set to ON to force the use of the static
boost libraries. Defaults to OFF.

Other Variables used by this module which you may want to set.

Boost_ADDITIONAL_VERSIONS A list of version numbers to use for searching
the boost include directory. Please see
the documentation above regarding this
annoying, but necessary variable :(

Boost_DEBUG Set this to TRUE to enable debugging output
of FindBoost.cmake if you are having problems.
Please enable this before filing any bug
reports.

Boost_DETAILED_FAILURE_MSG FindBoost doesn't output detailed information
about why it failed or how to fix the problem
unless this is set to TRUE or the REQUIRED
keyword is specified in find_package().
[Since CMake 2.8.0]

Boost_COMPILER Set this to the compiler suffix used by Boost
(e.g. "-gcc43") if FindBoost has problems finding
the proper Boost installation

These last three variables are available also as environment
variables:

BOOST_ROOT or BOOSTROOT The preferred installation prefix for searching for
Boost. Set this if the module has problems finding
the proper Boost installation.

BOOST_INCLUDEDIR Set this to the include directory of Boost, if the
module has problems finding the proper Boost installation

BOOST_LIBRARYDIR Set this to the lib directory of Boost, if the
module has problems finding the proper Boost installation

Variables defined by this module:

Boost_FOUND System has Boost, this means the include dir was
found, as well as all the libraries specified in
the COMPONENTS list.

Boost_INCLUDE_DIRS Boost include directories: not cached

Boost_INCLUDE_DIR This is almost the same as above, but this one is
cached and may be modified by advanced users

Boost_LIBRARIES Link to these to use the Boost libraries that you
specified: not cached

Boost_LIBRARY_DIRS The path to where the Boost library files are.

Boost_VERSION The version number of the boost libraries that
have been found, same as in version.hpp from Boost

Boost_LIB_VERSION The version number in filename form as
it's appended to the library filenames

Boost_MAJOR_VERSION major version number of boost
Boost_MINOR_VERSION minor version number of boost
Boost_SUBMINOR_VERSION subminor version number of boost

Boost_LIB_DIAGNOSTIC_DEFINITIONS [WIN32 Only] You can call
add_definitions(${Boost_LIB_DIAGNOSTIC_DEFINITIONS})
to have diagnostic information about Boost's
automatic linking outputted during compilation time.

For each component you specify in find_package(), the following
(UPPER-CASE) variables are set. You can use these variables if
you would like to pick and choose components for your targets
instead of just using Boost_LIBRARIES.

Boost_${COMPONENT}_FOUND True IF the Boost library "component" was found.

Boost_${COMPONENT}_LIBRARY Contains the libraries for the specified Boost
"component" (includes debug and optimized keywords
when needed).

FindBullet
Try to find the Bullet physics engine

This module defines the following variables

BULLET_FOUND - Was bullet found
BULLET_INCLUDE_DIRS - the Bullet include directories
BULLET_LIBRARIES - Link to this, by default it includes
all bullet components (Dynamics,
Collision, LinearMath, & SoftBody)

This module accepts the following variables

BULLET_ROOT - Can be set to bullet install path or Windows build path

FindCABLE
Find CABLE

This module finds if CABLE is installed and determines where the
include files and libraries are. This code sets the following
variables:

CABLE the path to the cable executable
CABLE_TCL_LIBRARY the path to the Tcl wrapper library
CABLE_INCLUDE_DIR the path to the include directory

To build Tcl wrappers, you should add shared library and link it
to ${CABLE_TCL_LIBRARY}. You should also add
${CABLE_INCLUDE_DIR} as an include directory.

FindCUDA
Tools for building CUDA C files: libraries and build dependen‐
cies.

This script locates the NVIDIA CUDA C tools. It should work on
linux, windows, and mac and should be reasonably up to date with
CUDA C releases.

This script makes use of the standard find_package arguments of
<VERSION>, REQUIRED and QUIET. CUDA_FOUND will report if an
acceptable version of CUDA was found.

The script will prompt the user to specify CUDA_TOOLKIT_ROOT_DIR
if the prefix cannot be determined by the location of nvcc in
the system path and REQUIRED is specified to find_package(). To
use a different installed version of the toolkit set the envi‐
ronment variable CUDA_BIN_PATH before running cmake (e.g.
CUDA_BIN_PATH=/usr/local/cuda1.0 instead of the default
/usr/local/cuda) or set CUDA_TOOLKIT_ROOT_DIR after configuring.
If you change the value of CUDA_TOOLKIT_ROOT_DIR, various compo‐
nents that depend on the path will be relocated.

It might be necessary to set CUDA_TOOLKIT_ROOT_DIR manually on
certain platforms, or to use a cuda runtime not installed in the
default location. In newer versions of the toolkit the cuda
library is included with the graphics driver- be sure that the
driver version matches what is needed by the cuda runtime ver‐
sion.

The following variables affect the behavior of the macros in the
script (in alphebetical order). Note that any of these flags
can be changed multiple times in the same directory before call‐
ing CUDA_ADD_EXECUTABLE, CUDA_ADD_LIBRARY, CUDA_COMPILE,
CUDA_COMPILE_PTX or CUDA_WRAP_SRCS.

CUDA_64_BIT_DEVICE_CODE (Default matches host bit size)
-- Set to ON to compile for 64 bit device code, OFF for 32 bit device code.
Note that making this different from the host code when generating object
or C files from CUDA code just won't work, because size_t gets defined by
nvcc in the generated source. If you compile to PTX and then load the
file yourself, you can mix bit sizes between device and host.

CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE (Default ON)
-- Set to ON if you want the custom build rule to be attached to the source
file in Visual Studio. Turn OFF if you add the same cuda file to multiple
targets.

This allows the user to build the target from the CUDA file; however, bad
things can happen if the CUDA source file is added to multiple targets.
When performing parallel builds it is possible for the custom build
command to be run more than once and in parallel causing cryptic build
errors. VS runs the rules for every source file in the target, and a
source can have only one rule no matter how many projects it is added to.
When the rule is run from multiple targets race conditions can occur on
the generated file. Eventually everything will get built, but if the user
is unaware of this behavior, there may be confusion. It would be nice if
this script could detect the reuse of source files across multiple targets
and turn the option off for the user, but no good solution could be found.

CUDA_BUILD_CUBIN (Default OFF)
-- Set to ON to enable and extra compilation pass with the -cubin option in
Device mode. The output is parsed and register, shared memory usage is
printed during build.

CUDA_BUILD_EMULATION (Default OFF for device mode)
-- Set to ON for Emulation mode. -D_DEVICEEMU is defined for CUDA C files
when CUDA_BUILD_EMULATION is TRUE.

CUDA_GENERATED_OUTPUT_DIR (Default CMAKE_CURRENT_BINARY_DIR)
-- Set to the path you wish to have the generated files placed. If it is
blank output files will be placed in CMAKE_CURRENT_BINARY_DIR.
Intermediate files will always be placed in
CMAKE_CURRENT_BINARY_DIR/CMakeFiles.

CUDA_HOST_COMPILATION_CPP (Default ON)
-- Set to OFF for C compilation of host code.

CUDA_NVCC_FLAGS
CUDA_NVCC_FLAGS_<CONFIG>
-- Additional NVCC command line arguments. NOTE: multiple arguments must be
semi-colon delimited (e.g. --compiler-options;-Wall)

CUDA_PROPAGATE_HOST_FLAGS (Default ON)
-- Set to ON to propagate CMAKE_{C,CXX}_FLAGS and their configuration
dependent counterparts (e.g. CMAKE_C_FLAGS_DEBUG) automatically to the
host compiler through nvcc's -Xcompiler flag. This helps make the
generated host code match the rest of the system better. Sometimes
certain flags give nvcc problems, and this will help you turn the flag
propagation off. This does not affect the flags supplied directly to nvcc
via CUDA_NVCC_FLAGS or through the OPTION flags specified through
CUDA_ADD_LIBRARY, CUDA_ADD_EXECUTABLE, or CUDA_WRAP_SRCS. Flags used for
shared library compilation are not affected by this flag.

CUDA_VERBOSE_BUILD (Default OFF)
-- Set to ON to see all the commands used when building the CUDA file. When
using a Makefile generator the value defaults to VERBOSE (run make
VERBOSE=1 to see output), although setting CUDA_VERBOSE_BUILD to ON will
always print the output.

The script creates the following macros (in alphebetical order):

CUDA_ADD_CUFFT_TO_TARGET( cuda_target )
-- Adds the cufft library to the target (can be any target). Handles whether
you are in emulation mode or not.

CUDA_ADD_CUBLAS_TO_TARGET( cuda_target )
-- Adds the cublas library to the target (can be any target). Handles
whether you are in emulation mode or not.

CUDA_ADD_EXECUTABLE( cuda_target file0 file1 ...
[WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
-- Creates an executable "cuda_target" which is made up of the files
specified. All of the non CUDA C files are compiled using the standard
build rules specified by CMAKE and the cuda files are compiled to object
files using nvcc and the host compiler. In addition CUDA_INCLUDE_DIRS is
added automatically to include_directories(). Some standard CMake target
calls can be used on the target after calling this macro
(e.g. set_target_properties and target_link_libraries), but setting
properties that adjust compilation flags will not affect code compiled by
nvcc. Such flags should be modified before calling CUDA_ADD_EXECUTABLE,
CUDA_ADD_LIBRARY or CUDA_WRAP_SRCS.

CUDA_ADD_LIBRARY( cuda_target file0 file1 ...
[STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
-- Same as CUDA_ADD_EXECUTABLE except that a library is created.

CUDA_BUILD_CLEAN_TARGET()
-- Creates a convience target that deletes all the dependency files
generated. You should make clean after running this target to ensure the
dependency files get regenerated.

CUDA_COMPILE( generated_files file0 file1 ... [STATIC | SHARED | MODULE]
[OPTIONS ...] )
-- Returns a list of generated files from the input source files to be used
with ADD_LIBRARY or ADD_EXECUTABLE.

CUDA_COMPILE_PTX( generated_files file0 file1 ... [OPTIONS ...] )
-- Returns a list of PTX files generated from the input source files.

CUDA_INCLUDE_DIRECTORIES( path0 path1 ... )
-- Sets the directories that should be passed to nvcc
(e.g. nvcc -Ipath0 -Ipath1 ... ). These paths usually contain other .cu
files.

CUDA_WRAP_SRCS ( cuda_target format generated_files file0 file1 ...
[STATIC | SHARED | MODULE] [OPTIONS ...] )
-- This is where all the magic happens. CUDA_ADD_EXECUTABLE,
CUDA_ADD_LIBRARY, CUDA_COMPILE, and CUDA_COMPILE_PTX all call this
function under the hood.

Given the list of files (file0 file1 ... fileN) this macro generates
custom commands that generate either PTX or linkable objects (use "PTX" or
"OBJ" for the format argument to switch). Files that don't end with .cu
or have the HEADER_FILE_ONLY property are ignored.

The arguments passed in after OPTIONS are extra command line options to
give to nvcc. You can also specify per configuration options by
specifying the name of the configuration followed by the options. General
options must preceed configuration specific options. Not all
configurations need to be specified, only the ones provided will be used.

OPTIONS -DFLAG=2 "-DFLAG_OTHER=space in flag"
DEBUG -g
RELEASE --use_fast_math
RELWITHDEBINFO --use_fast_math;-g
MINSIZEREL --use_fast_math

For certain configurations (namely VS generating object files with
CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE set to ON), no generated file will
be produced for the given cuda file. This is because when you add the
cuda file to Visual Studio it knows that this file produces an object file
and will link in the resulting object file automatically.

This script will also generate a separate cmake script that is used at
build time to invoke nvcc. This is for serveral reasons.

1. nvcc can return negative numbers as return values which confuses
Visual Studio into thinking that the command succeeded. The script now
checks the error codes and produces errors when there was a problem.

2. nvcc has been known to not delete incomplete results when it
encounters problems. This confuses build systems into thinking the
target was generated when in fact an unusable file exists. The script
now deletes the output files if there was an error.

3. By putting all the options that affect the build into a file and then
make the build rule dependent on the file, the output files will be
regenerated when the options change.

This script also looks at optional arguments STATIC, SHARED, or MODULE to
determine when to target the object compilation for a shared library.
BUILD_SHARED_LIBS is ignored in CUDA_WRAP_SRCS, but it is respected in
CUDA_ADD_LIBRARY. On some systems special flags are added for building
objects intended for shared libraries. A preprocessor macro,
<target_name>_EXPORTS is defined when a shared library compilation is
detected.

Flags passed into add_definitions with -D or /D are passed along to nvcc.

The script defines the following variables:

CUDA_VERSION_MAJOR -- The major version of cuda as reported by nvcc.
CUDA_VERSION_MINOR -- The minor version.
CUDA_VERSION
CUDA_VERSION_STRING -- CUDA_VERSION_MAJOR.CUDA_VERSION_MINOR

CUDA_TOOLKIT_ROOT_DIR -- Path to the CUDA Toolkit (defined if not set).
CUDA_SDK_ROOT_DIR -- Path to the CUDA SDK. Use this to find files in the
SDK. This script will not directly support finding
specific libraries or headers, as that isn't
supported by NVIDIA. If you want to change
libraries when the path changes see the
FindCUDA.cmake script for an example of how to clear
these variables. There are also examples of how to
use the CUDA_SDK_ROOT_DIR to locate headers or
libraries, if you so choose (at your own risk).
CUDA_INCLUDE_DIRS -- Include directory for cuda headers. Added automatically
for CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY.
CUDA_LIBRARIES -- Cuda RT library.
CUDA_CUFFT_LIBRARIES -- Device or emulation library for the Cuda FFT
implementation (alternative to:
CUDA_ADD_CUFFT_TO_TARGET macro)
CUDA_CUBLAS_LIBRARIES -- Device or emulation library for the Cuda BLAS
implementation (alterative to:
CUDA_ADD_CUBLAS_TO_TARGET macro).

This module locates the developer's image library. http://ope‐
nil.sourceforge.net/

This module sets: IL_LIBRARIES the name of the IL library. These
include the full path to the core DevIL library. This one has to
be linked into the application. ILU_LIBRARIES the name of the
ILU library. Again, the full path. This library is for filters
and effects, not actual loading. It doesn't have to be linked if
the functionality it provides is not used. ILUT_LIBRARIES the
name of the ILUT library. Full path. This part of the library
interfaces with OpenGL. It is not strictly needed in applica‐
tions. IL_INCLUDE_DIR where to find the il.h, ilu.h and ilut.h
files. IL_FOUND this is set to TRUE if all the above variables
were set. This will be set to false if ILU or ILUT are not
found, even if they are not needed. In most systems, if one
library is found all the others are as well. That's the way the
DevIL developers release it.

FindDoxygen
This module looks for Doxygen and the path to Graphviz's dot

Doxygen is a documentation generation tool. Please see

build rules

The module defines the following variables:

FLEX_FOUND - true is flex executable is found
FLEX_EXECUTABLE - the path to the flex executable
FLEX_VERSION - the version of flex
FLEX_LIBRARIES - The flex libraries

If flex is found on the system, the module provides the macro:

FLEX_TARGET(Name FlexInput FlexOutput [COMPILE_FLAGS <string>])

which creates a custom command to generate the <FlexOutput>
file from the <FlexInput> file. If COMPILE_FLAGS option is
specified, the next parameter is added to the flex command
line. Name is an alias used to get details of this custom
command. Indeed the macro defines the following variables:

FLEX_${Name}_DEFINED - true is the macro ran successfully
FLEX_${Name}_OUTPUTS - the source file generated by the custom rule, an
alias for FlexOutput
FLEX_${Name}_INPUT - the flex source file, an alias for ${FlexInput}

Flex scanners oftenly use tokens defined by Bison: the code
generated by Flex depends of the header generated by Bison.
This module also defines a macro:

ADD_FLEX_BISON_DEPENDENCY(FlexTarget BisonTarget)

which adds the required dependency between a scanner and a
parser where <FlexTarget> and <BisonTarget> are the first
parameters of respectively FLEX_TARGET and BISON_TARGET macros.

====================================================================
Example:

find_package(BISON)
find_package(FLEX)

BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp
FLEX_TARGET(MyScanner lexer.l ${CMAKE_CURRENT_BIANRY_DIR}/lexer.cpp)
ADD_FLEX_BISON_DEPENDENCY(MyScanner MyParser)

the following values:

GETTEXT_MSGMERGE_EXECUTABLE: the full path to the msgmerge tool.
GETTEXT_MSGFMT_EXECUTABLE: the full path to the msgfmt tool.
GETTEXT_FOUND: True if gettext has been found.

Additionally it provides the following macros: GETTEXT_CRE‐
ATE_TRANSLATIONS ( outputFile [ALL] file1 ... fileN )

GNUPLOT_EXECUTABLE - the Gnuplot executable

FindHDF5
Find HDF5, a library for reading and writing self describing
array data.

This module invokes the HDF5 wrapper compiler that should be
installed alongside HDF5. Depending upon the HDF5 Configura‐
tion, the wrapper compiler is called either h5cc or h5pcc. If
this succeeds, the module will then call the compiler with the
-show argument to see what flags are used when compiling an HDF5
client application.

The module will optionally accept the COMPONENTS argument. If
no COMPONENTS are specified, then the find module will default
to finding only the HDF5 C library. If one or more COMPONENTS
are specified, the module will attempt to find the language
bindings for the specified components. Currently, the only
valid components are C and CXX. The module does not yet support
finding the Fortran bindings. If the COMPONENTS argument is not
given, the module will attempt to find only the C bindings.

On UNIX systems, this module will read the variable
HDF5_USE_STATIC_LIBRARIES to determine whether or not to prefer
a static link to a dynamic link for HDF5 and all of it's depen‐
dencies. To use this feature, make sure that the
HDF5_USE_STATIC_LIBRARIES variable is set before the call to
find_package.

To provide the module with a hint about where to find your HDF5
installation, you can set the environment variable HDF5_ROOT.
The Find module will then look in this path when searching for
HDF5 executables, paths, and libraries.

In addition to finding the includes and libraries required to
compile an HDF5 client application, this module also makes an
effort to find tools that come with the HDF5 distribution that
may be useful for regression testing.

This module will define the following variables:

HDF5_INCLUDE_DIRS - Location of the hdf5 includes
HDF5_INCLUDE_DIR - Location of the hdf5 includes (deprecated)
HDF5_DEFINITIONS - Required compiler definitions for HDF5
HDF5_C_LIBRARIES - Required libraries for the HDF5 C bindings.
HDF5_CXX_LIBRARIES - Required libraries for the HDF5 C++ bindings
HDF5_LIBRARIES - Required libraries for all requested bindings
HDF5_FOUND - true if HDF5 was found on the system
HDF5_LIBRARY_DIRS - the full set of library directories
HDF5_IS_PARALLEL - Whether or not HDF5 was found with parallel IO support
HDF5_C_COMPILER_EXECUTABLE - the path to the HDF5 C wrapper compiler
HDF5_CXX_COMPILER_EXECUTABLE - the path to the HDF5 C++ wrapper compiler
HDF5_DIFF_EXECUTABLE - the path to the HDF5 dataset comparison tool

FindITK
Find an ITK installation or build tree.

FindImageMagick
Find the ImageMagick binary suite.

include, but are not limited to (future versions of ImageMagick
might have additional components not listed here):

animate
compare
composite
conjure
convert
display
identify
import
mogrify
montage
stream

If no component is specified in the FIND_PACKAGE call, then it
only searches for the ImageMagick executable directory. This
code defines the following variables:

ImageMagick_FOUND - TRUE if all components are found.
ImageMagick_EXECUTABLE_DIR - Full path to executables directory.
ImageMagick_<component>_FOUND - TRUE if <component> is found.
ImageMagick_<component>_EXECUTABLE - Full path to <component> executable.

There are also components for the following ImageMagick APIs:

Magick++
MagickWand
MagickCore

For these components the following variables are set:

ImageMagick_FOUND - TRUE if all components are found.
ImageMagick_INCLUDE_DIRS - Full paths to all include dirs.
ImageMagick_LIBRARIES - Full paths to all libraries.
ImageMagick_<component>_FOUND - TRUE if <component> is found.
ImageMagick_<component>_INCLUDE_DIRS - Full path to <component> include dirs.

Example Usages:

FIND_PACKAGE(ImageMagick)
FIND_PACKAGE(ImageMagick COMPONENTS convert)
FIND_PACKAGE(ImageMagick COMPONENTS convert mogrify display)
FIND_PACKAGE(ImageMagick COMPONENTS Magick++)
FIND_PACKAGE(ImageMagick COMPONENTS Magick++ convert)

Note that the standard FIND_PACKAGE features are supported
(i.e., QUIET, REQUIRED, etc.).

FindJNI
Find JNI java libraries.

This module finds if Java is installed and determines where the
include files and libraries are. It also determines what the
name of the library is. This code sets the following variables:

JNI_INCLUDE_DIRS = the include dirs to use
JNI_LIBRARIES = the libraries to use

FindJava
Find Java

This module finds if Java is installed and determines where the
include files and libraries are. This code sets the following
variables:

Java_JAVA_EXECUTABLE = the full path to the Java runtime
Java_JAVAC_EXECUTABLE = the full path to the Java compiler
Java_JAR_EXECUTABLE = the full path to the Java archiver
Java_VERSION_STRING = Version of the package found (java version), eg. 1.6.0_12
Java_VERSION_MAJOR = The major version of the package found.

Java_VERSION_PATCH = The patch version of the package found.
Java_VERSION_TWEAK = The tweak version of the package found (after '_')
Java_VERSION = This is set to: $major.$minor.$patch(.$tweak)

NOTE: ${Java_VERSION} and ${Java_VERSION_STRING} are not guaran‐
teed to be identical. For example some java version may return:
Java_VERSION_STRING = 1.5.0_17 and Java_VERSION =
1.5.0.17

another example is the Java OEM, with: Java_VERSION_STRING =
1.6.0-oem and Java_VERSION = 1.6.0

NOTE: At the moment this script will look for javac and jar com‐
ponent, which means it will fail if javac or jar is not found.:w

SRCS_VAR is always the variable which contains the list of
source files for your application or library.

KDE3_AUTOMOC(file1 ... fileN)

Call this if you want to have automatic moc file handling.
This means if you include "foo.moc" in the source file foo.cpp
a moc file for the header foo.h will be created automatically.
You can set the property SKIP_AUTOMAKE using SET_SOURCE_FILES_PROPERTIES()
to exclude some files in the list from being processed.

KDE3_ADD_MOC_FILES(SRCS_VAR file1 ... fileN )

If you don't use the KDE3_AUTOMOC() macro, for the files
listed here moc files will be created (named "foo.moc.cpp")

KDE3_ADD_DCOP_SKELS(SRCS_VAR header1.h ... headerN.h )

Use this to generate DCOP skeletions from the listed headers.

KDE3_ADD_DCOP_STUBS(SRCS_VAR header1.h ... headerN.h )

Use this to generate DCOP stubs from the listed headers.

KDE3_ADD_UI_FILES(SRCS_VAR file1.ui ... fileN.ui )

Use this to add the Qt designer ui files to your application/library.

KDE3_ADD_KCFG_FILES(SRCS_VAR file1.kcfgc ... fileN.kcfgc )

Use this to add KDE kconfig compiler files to your application/library.

KDE3_INSTALL_LIBTOOL_FILE(target)

This will create and install a simple libtool file for the given target.

KDE3_ADD_EXECUTABLE(name file1 ... fileN )

Currently identical to ADD_EXECUTABLE(), may provide some advanced features in the future.

KDE3_ADD_KPART(name [WITH_PREFIX] file1 ... fileN )

Create a KDE plugin (KPart, kioslave, etc.) from the given source files.
If WITH_PREFIX is given, the resulting plugin will have the prefix "lib", otherwise it won't.
It creates and installs an appropriate libtool la-file.

KDE3_ADD_KDEINIT_EXECUTABLE(name file1 ... fileN )

Create a KDE application in the form of a module loadable via kdeinit.
A library named kdeinit_<name> will be created and a small executable which links to it.

The option KDE3_ENABLE_FINAL to enable all-in-one compilation is
no longer supported.

FindMPI
Message Passing Interface (MPI) module.

The Message Passing Interface (MPI) is a library used to write
high-performance parallel applications that use message passing,
and is typically deployed on a cluster. MPI is a standard inter‐
face (defined by the MPI forum) for which many implementations
are available. All of these implementations have somewhat dif‐
ferent compilation approaches (different include paths,
libraries to link against, etc.), and this module tries to
smooth out those differences.

This module will set the following variables:

MPI_FOUND TRUE if we have found MPI
MPI_COMPILE_FLAGS Compilation flags for MPI programs
MPI_INCLUDE_PATH Include path(s) for MPI header
MPI_LINK_FLAGS Linking flags for MPI programs
MPI_LIBRARY First MPI library to link against (cached)
MPI_EXTRA_LIBRARY Extra MPI libraries to link against (cached)
MPI_LIBRARIES All libraries to link MPI programs against
MPIEXEC Executable for running MPI programs
MPIEXEC_NUMPROC_FLAG Flag to pass to MPIEXEC before giving it the
number of processors to run on
MPIEXEC_PREFLAGS Flags to pass to MPIEXEC directly before the
executable to run.
MPIEXEC_POSTFLAGS Flags to pass to MPIEXEC after all other flags.

This module will attempt to auto-detect these settings, first by
looking for a MPI compiler, which many MPI implementations pro‐
vide as a pass-through to the native compiler to simplify the
compilation of MPI programs. The MPI compiler is stored in the
cache variable MPI_COMPILER, and will attempt to look for com‐
monly-named drivers mpic++, mpicxx, mpiCC, or mpicc. If the com‐
piler driver is found and recognized, it will be used to set all
of the module variables. To skip this auto-detection, set
MPI_LIBRARY and MPI_INCLUDE_PATH in the CMake cache.

If no compiler driver is found or the compiler driver is not
recognized, this module will then search for common include
paths and library names to try to detect MPI.

If CMake initially finds a different MPI than was intended, and
you want to use the MPI compiler auto-detection for a different
MPI implementation, set MPI_COMPILER to the MPI compiler driver
you want to use (e.g., mpicxx) and then set MPI_LIBRARY to the
string MPI_LIBRARY-NOTFOUND. When you re-configure, auto-detec‐
tion of MPI will run again with the newly-specified MPI_COM‐
PILER.

When using MPIEXEC to execute MPI applications, you should typi‐
cally use all of the MPIEXEC flags as follows:

${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS ${MPIEXEC_PREFLAGS} EXECUTABLE
${MPIEXEC_POSTFLAGS} ARGS

where PROCS is the number of processors on which to execute the
program, EXECUTABLE is the MPI program, and ARGS are the argu‐
ments to pass to the MPI program.

will have to change the cache values of OPENGL_glu_LIBRARY and
OPENGL_gl_LIBRARY to use OpenGL with X11 on OSX

FindOpenMP
Finds OpenMP support

This module can be used to detect OpenMP support in a compiler.
If the compiler supports OpenMP, the flags required to compile
with openmp support are set.

The following variables are set:

OpenMP_C_FLAGS - flags to add to the C compiler for OpenMP support
OpenMP_CXX_FLAGS - flags to add to the CXX compiler for OpenMP support

FindOpenSceneGraph
Find OpenSceneGraph

This module searches for the OpenSceneGraph core "osg" library
as well as OpenThreads, and whatever additional COMPONENTS
(nodekits) that you specify.

See http://www.openscenegraph.org

NOTE: To use this module effectively you must either require
CMake >= 2.6.3 with cmake_minimum_required(VERSION 2.6.3) or
download and place FindOpenThreads.cmake, Findosg_func‐
tions.cmake, Findosg.cmake, and Find<etc>.cmake files into your
CMAKE_MODULE_PATH.

==================================

This module accepts the following variables (note mixed case)

OpenSceneGraph_DEBUG - Enable debugging output

OpenSceneGraph_MARK_AS_ADVANCED - Mark cache variables as advanced
automatically

The following environment variables are also respected for find‐
ing the OSG and it's various components. CMAKE_PREFIX_PATH can
also be used for this (see find_library() CMake documentation).

<MODULE>_DIR (where MODULE is of the form "OSGVOLUME" and there is a FindosgVolume.cmake file)
OSG_DIR
OSGDIR
OSG_ROOT

This module defines the following output variables:

OPENSCENEGRAPH_FOUND - Was the OSG and all of the specified components found?

OPENSCENEGRAPH_VERSION - The version of the OSG which was found

OPENSCENEGRAPH_INCLUDE_DIRS - Where to find the headers

OPENSCENEGRAPH_LIBRARIES - The OSG libraries

================================== Example Usage:

find_package(OpenSceneGraph 2.0.0 REQUIRED osgDB osgUtil)
# libOpenThreads & libosg automatically searched
include_directories(${OPENSCENEGRAPH_INCLUDE_DIRS})

add_executable(foo foo.cc)
target_link_libraries(foo ${OPENSCENEGRAPH_LIBRARIES})

FindOpenThreads

OpenThreads is a C++ based threading library. Its largest user‐
base seems to OpenSceneGraph so you might notice I accept
OSGDIR as an environment path. I consider this part of the Find‐
osg* suite used to find OpenSceneGraph components. Each compo‐
nent is separate and you must opt in to each module.

Locate OpenThreads This module defines OPENTHREADS_LIBRARY
OPENTHREADS_FOUND, if false, do not try to link to OpenThreads
OPENTHREADS_INCLUDE_DIR, where to find the headers

$OPENTHREADS_DIR is an environment variable that would corre‐
spond to the ./configure --prefix=$OPENTHREADS_DIR used in
building osg.

FindPHP4
Find PHP4

This module finds if PHP4 is installed and determines where the
include files and libraries are. It also determines what the
name of the library is. This code sets the following variables:

PHP4_INCLUDE_PATH = path to where php.h can be found
PHP4_EXECUTABLE = full path to the php4 binary

FindPNG
Find the native PNG includes and library

This module defines

PNG_INCLUDE_DIR, where to find png.h, etc.
PNG_LIBRARIES, the libraries to link against to use PNG.
PNG_DEFINITIONS - You should add_definitons(${PNG_DEFINITIONS}) before compiling code that includes png library files.
PNG_FOUND, If false, do not try to use PNG.

also defined, but not for general use are

PNG_LIBRARY, where to find the PNG library.

None of the above will be defined unles zlib can be found. PNG
depends on Zlib

FindPackageHandleStandardArgs

FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME (DEFAULT_MSG|"Custom
failure message") VAR1 ... )

This macro is intended to be used in FindXXX.cmake modules files.
It handles the REQUIRED and QUIET argument to FIND_PACKAGE() and
it also sets the <UPPERCASED_NAME>_FOUND variable.
The package is found if all variables listed are TRUE.
Example:

FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2 DEFAULT_MSG LIBXML2_LIBRARIES LIBXML2_INCLUDE_DIR)

LibXml2 is considered to be found, if both LIBXML2_LIBRARIES and
LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to TRUE.
If it is not found and REQUIRED was used, it fails with FATAL_ERROR,
independent whether QUIET was used or not.
If it is found, the location is reported using the VAR1 argument, so
here a message "Found LibXml2: /usr/lib/libxml2.so" will be printed out.
If the second argument is DEFAULT_MSG, the message in the failure case will
be "Could NOT find LibXml2", if you don't like this message you can specify
your own custom failure message there.

FindPackageMessage

FIND_PACKAGE_MESSAGE(<name> "message for user" "find result
details")

This macro is intended to be used in FindXXX.cmake modules
files. It will print a message once for each unique find result.
This is useful for telling the user where a package was found.
The first argument specifies the name (XXX) of the package. The
second argument specifies the message to display. The third
argument lists details about the find result so that if they
change the message will be displayed again. The macro also obeys
the QUIET argument to the find_package command.

Example:

IF(X11_FOUND)
FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
"[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
ELSE(X11_FOUND)
...
ENDIF(X11_FOUND)

FindPerl

PERL_EXECUTABLE - the full path to perl
PERL_FOUND - If false, don't attempt to use perl.

FindPerlLibs

PERLLIBS_FOUND = True if perl.h & libperl were found
PERL_INCLUDE_PATH = path to where perl.h is found
PERL_LIBRARY = path to libperl
PERL_EXECUTABLE = full path to the perl binary

FindPike
Find Pike

This module finds if PIKE is installed and determines where the
include files and libraries are. It also determines what the
name of the library is. This code sets the following variables:

PIKE_INCLUDE_PATH = path to where program.h is found
PIKE_EXECUTABLE = full path to the pike binary

FindPkgConfig
a pkg-config module for CMake

Usage:

pkg_check_modules(<PREFIX> [REQUIRED] <MODULE> [<MODULE>]*)
checks for all the given modules

pkg_search_module(<PREFIX> [REQUIRED] <MODULE> [<MODULE>]*)
checks for given modules and uses the first working one

When the 'REQUIRED' argument was set, macros will fail with an
error when module(s) could not be found

It sets the following variables:

PKG_CONFIG_FOUND ... true if pkg-config works on the system
PKG_CONFIG_EXECUTABLE ... pathname of the pkg-config program
<PREFIX>_FOUND ... set to 1 if module(s) exist

For the following variables two sets of values exist; first one
is the common one and has the given PREFIX. The second set con‐
tains flags which are given out when pkgconfig was called with
the '--static' option.

<XPREFIX>_LIBRARIES ... only the libraries (w/o the '-l')
<XPREFIX>_LIBRARY_DIRS ... the paths of the libraries (w/o the '-L')
<XPREFIX>_LDFLAGS ... all required linker flags
<XPREFIX>_LDFLAGS_OTHER ... all other linker flags
<XPREFIX>_INCLUDE_DIRS ... the '-I' preprocessor flags (w/o the '-I')
<XPREFIX>_CFLAGS ... all required cflags
<XPREFIX>_CFLAGS_OTHER ... the other compiler flags

<XPREFIX> = <PREFIX> for common case
<XPREFIX> = <PREFIX>_STATIC for static linking

There are some special variables whose prefix depends on the
count of given modules. When there is only one module, <PREFIX>
stays unchanged. When there are multiple modules, the prefix
will be changed to <PREFIX>_<MODNAME>:

<XPREFIX>_VERSION ... version of the module
<XPREFIX>_PREFIX ... prefix-directory of the module
<XPREFIX>_INCLUDEDIR ... include-dir of the module
<XPREFIX>_LIBDIR ... lib-dir of the module

<XPREFIX> = <PREFIX> when |MODULES| == 1, else
<XPREFIX> = <PREFIX>_<MODNAME>

A <MODULE> parameter can have the following formats:

{MODNAME} ... matches any version
{MODNAME}>={VERSION} ... at least version <VERSION> is required
{MODNAME}={VERSION} ... exactly version <VERSION> is required
{MODNAME}<={VERSION} ... modules must not be newer than <VERSION>

Examples

pkg_check_modules (GLIB2 glib-2.0)

pkg_check_modules (GLIB2 glib-2.0>=2.10)
requires at least version 2.10 of glib2 and defines e.g.
GLIB2_VERSION=2.10.3

pkg_check_modules (FOO glib-2.0>=2.10 gtk+-2.0)
requires both glib2 and gtk2, and defines e.g.
FOO_glib-2.0_VERSION=2.10.3
FOO_gtk+-2.0_VERSION=2.8.20

pkg_check_modules (XRENDER REQUIRED xrender)
defines e.g.:
XRENDER_LIBRARIES=Xrender;X11
XRENDER_STATIC_LIBRARIES=Xrender;X11;pthread;Xau;Xdmcp

pkg_search_module (BAR libxml-2.0 libxml2 libxml>=2)

FindProducer

Though Producer isn't directly part of OpenSceneGraph, its pri‐
mary user is OSG so I consider this part of the Findosg* suite
used to find OpenSceneGraph components. You'll notice that I
accept OSGDIR as an environment path.

Each component is separate and you must opt in to each module.
You must also opt into OpenGL (and OpenThreads?) as these mod‐
ules won't do it for you. This is to allow you control over your
own system piece by piece in case you need to opt out of cer‐
tain components or change the Find behavior for a particular
module (perhaps because the default FindOpenGL.cmake module
doesn't work with your system as an example). If you want to use
a more convenient module that includes everything, use the Find‐
OpenSceneGraph.cmake instead of the Findosg*.cmake modules.

Locate Producer This module defines PRODUCER_LIBRARY PRO‐
DUCER_FOUND, if false, do not try to link to Producer PRO‐
DUCER_INCLUDE_DIR, where to find the headers

$PRODUCER_DIR is an environment variable that would correspond
to the ./configure --prefix=$PRODUCER_DIR used in building osg.

FindQt Searches for all installed versions of QT.

This should only be used if your project can work with multiple
versions of QT. If not, you should just directly use FindQt4 or
FindQt3. If multiple versions of QT are found on the machine,
then The user must set the option DESIRED_QT_VERSION to the ver‐
sion they want to use. If only one version of qt is found on
the machine, then the DESIRED_QT_VERSION is set to that version
and the matching FindQt3 or FindQt4 module is included. Once
the user sets DESIRED_QT_VERSION, then the FindQt3 or FindQt4
module is included.

QT_REQUIRED if this is set to TRUE then if CMake can
not find QT4 or QT3 an error is raised
and a message is sent to the user.

DESIRED_QT_VERSION OPTION is created
QT4_INSTALLED is set to TRUE if qt4 is found.
QT3_INSTALLED is set to TRUE if qt3 is found.

FindQt3

to TRUE

Also defined, but not for general use are:

QT_MOC_EXECUTABLE, where to find the moc tool.
QT_UIC_EXECUTABLE, where to find the uic tool.
QT_QT_LIBRARY, where to find the Qt library.
QT_QTMAIN_LIBRARY, where to find the qtmain
library. This is only required by Qt3 on Windows.

FindQt4
Find QT 4

This module can be used to find Qt4. The most important issue is
that the Qt4 qmake is available via the system path. This qmake
is then used to detect basically everything else. This module
defines a number of key variables and macros. The variable
QT_USE_FILE is set which is the path to a CMake file that can be
included to compile Qt 4 applications and libraries. It sets
up the compilation environment for include directories, pre‐
processor defines and populates a QT_LIBRARIES variable.

Typical usage could be something like:

find_package(Qt4 4.4.3 COMPONENTS QtCore QtGui QtXml REQUIRED )
include(${QT_USE_FILE})
add_executable(myexe main.cpp)
target_link_libraries(myexe ${QT_LIBRARIES})

The minimum required version can be specified using the standard
find_package()-syntax (see example above). For compatibility
with older versions of FindQt4.cmake it is also possible to set
the variable QT_MIN_VERSION to the minimum required version of
Qt4 before the find_package(Qt4) command. If both are used,
the version used in the find_package() command overrides the one
from QT_MIN_VERSION.

When using the components argument, QT_USE_QT* variables are
automatically set for the QT_USE_FILE to pick up. If one wishes
to manually set them, the available ones to set include:

QT_DONT_USE_QTCORE
QT_DONT_USE_QTGUI
QT_USE_QT3SUPPORT
QT_USE_QTASSISTANT
QT_USE_QAXCONTAINER
QT_USE_QAXSERVER
QT_USE_QTDESIGNER
QT_USE_QTMOTIF
QT_USE_QTMAIN
QT_USE_QTMULTIMEDIA
QT_USE_QTNETWORK
QT_USE_QTNSPLUGIN
QT_USE_QTOPENGL
QT_USE_QTSQL
QT_USE_QTXML
QT_USE_QTSVG
QT_USE_QTTEST
QT_USE_QTUITOOLS
QT_USE_QTDBUS
QT_USE_QTSCRIPT
QT_USE_QTASSISTANTCLIENT
QT_USE_QTHELP
QT_USE_QTWEBKIT
QT_USE_QTXMLPATTERNS
QT_USE_PHONON
QT_USE_QTSCRIPTTOOLS
QT_USE_QTDECLARATIVE

QT_USE_IMPORTED_TARGETS
If this variable is set to TRUE, FindQt4.cmake will create imported
library targets for the various Qt libraries and set the
library variables like QT_QTCORE_LIBRARY to point at these imported
targets instead of the library file on disk. This provides much better
handling of the release and debug versions of the Qt libraries and is
also always backwards compatible, except for the case that dependencies
of libraries are exported, these will then also list the names of the
imported targets as dependency and not the file location on disk. This
is much more flexible, but requires that FindQt4.cmake is executed before
such an exported dependency file is processed.

There are also some files that need processing by some Qt tools
such as moc and uic. Listed below are macros that may be used
to process those files.

macro QT4_WRAP_CPP(outfiles inputfile ... OPTIONS ...)
create moc code from a list of files containing Qt class with
the Q_OBJECT declaration. Per-direcotry preprocessor definitions
are also added. Options may be given to moc, such as those found
when executing "moc -help".

macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...)
create code from a list of Qt designer ui files.
Options may be given to uic, such as those found
when executing "uic -help"

macro QT4_ADD_RESOURCES(outfiles inputfile ... OPTIONS ...)
create code from a list of Qt resource files.
Options may be given to rcc, such as those found
when executing "rcc -help"

macro QT4_GENERATE_MOC(inputfile outputfile )
creates a rule to run moc on infile and create outfile.
Use this if for some reason QT4_WRAP_CPP() isn't appropriate, e.g.
because you need a custom filename for the moc file or something similar.

macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... )
This macro is still experimental.
It can be used to have moc automatically handled.
So if you have the files foo.h and foo.cpp, and in foo.h a
a class uses the Q_OBJECT macro, moc has to run on it. If you don't
want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert
#include "foo.moc"
in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will the
scan all listed files at cmake-time for such included moc files and if it finds
them cause a rule to be generated to run moc at build time on the
accompanying header file foo.h.
If a source file has the SKIP_AUTOMOC property set it will be ignored by this macro.

macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename)
create a the interface header and implementation files with the
given basename from the given interface xml file and add it to
the list of sources

macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... )
create the interface header and implementation files
for all listed interface xml files
the name will be automatically determined from the name of the xml file

macro QT4_ADD_DBUS_ADAPTOR(outfiles xmlfile parentheader parentclassname [basename] [classname])
create a dbus adaptor (header and implementation file) from the xml file
describing the interface, and add it to the list of sources. The adaptor
forwards the calls to a parent class, defined in parentheader and named
parentclassname. The name of the generated files will be
<basename>adaptor.{cpp,h} where basename defaults to the basename of the xml file.
If <classname> is provided, then it will be used as the classname of the
adaptor itself.

macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] OPTIONS ...)
generate the xml interface file from the given header.
If the optional argument interfacename is omitted, the name of the
interface file is constructed from the basename of the header with
the suffix .xml appended.
Options may be given to qdbuscpp2xml, such as those found when executing "qdbuscpp2xml --help"

macro QT4_CREATE_TRANSLATION( qm_files directories ... sources ...
ts_files ... OPTIONS ...)
out: qm_files
in: directories sources ts_files
options: flags to pass to lupdate, such as -extensions to specify
extensions for a directory scan.
generates commands to create .ts (vie lupdate) and .qm
(via lrelease) - files from directories and/or sources. The ts files are
created and/or updated in the source tree (unless given with full paths).
The qm files are generated in the build tree.
Updating the translations can be done by adding the qm_files
to the source list of your library/executable, so they are
always updated, or by adding a custom target to control when
they get updated/generated.

macro QT4_ADD_TRANSLATION( qm_files ts_files ... )
out: qm_files
in: ts_files
generates commands to create .qm from .ts - files. The generated
filenames can be found in qm_files. The ts_files
must exists and are not updated in any way.

QT_UIC_EXECUTABLE Where to find the uic tool.
QT_UIC3_EXECUTABLE Where to find the uic3 tool.
QT_RCC_EXECUTABLE Where to find the rcc tool

These are around for backwards compatibility they will be set

QT_WRAP_CPP Set true if QT_MOC_EXECUTABLE is found
QT_WRAP_UI Set true if QT_UIC_EXECUTABLE is found

These variables do _NOT_ have any effect anymore (compared to
FindQt.cmake)

QT_MT_REQUIRED Qt4 is now always multithreaded

These variables are set to "" Because Qt structure changed
(They make no sense in Qt4)

QT_QT_LIBRARY Qt-Library is now split

FindQuickTime

Locate QuickTime This module defines QUICKTIME_LIBRARY QUICK‐
TIME_FOUND, if false, do not try to link to gdal QUICK‐
TIME_INCLUDE_DIR, where to find the headers

$QUICKTIME_DIR is an environment variable that would correspond
to the ./configure --prefix=$QUICKTIME_DIR

Created by Eric Wing.

FindRTI
Try to find M&S HLA RTI libraries

This module finds if any HLA RTI is installed and locates the
standard RTI include files and libraries.

RTI is a simulation infrastructure standardized by IEEE and
SISO. It has a well defined C++ API that assures that simulation
applications are independent on a particular RTI implementation.

http://en.wikipedia.org/wiki/Run-Time_Infrastructure_(simulation)

This code sets the following variables:

RTI_INCLUDE_DIR = the directory where RTI includes file are found
RTI_LIBRARIES = The libraries to link against to use RTI
RTI_DEFINITIONS = -DRTI_USES_STD_FSTREAM
RTI_FOUND = Set to FALSE if any HLA RTI was not found

Report problems to <certi-devel@nongnu.org>

FindRuby
Find Ruby

This module finds if Ruby is installed and determines where the
include files and libraries are. Ruby 1.8 and 1.9 are supported.
The minimum required version specified in the find_package()
command is honored. It also determines what the name of the
library is. This code sets the following variables:

RUBY_EXECUTABLE = full path to the ruby binary
RUBY_INCLUDE_DIRS = include dirs to be used when using the ruby library
RUBY_LIBRARY = full path to the ruby library
RUBY_VERSION = the version of ruby which was found, e.g. "1.8.7"
RUBY_FOUND = set to true if ruby ws found successfully

RUBY_INCLUDE_PATH = same as RUBY_INCLUDE_DIRS, only provided for compatibility reasons, don't use it

FindSDL

Locate SDL library This module defines SDL_LIBRARY, the name of
the library to link against SDL_FOUND, if false, do not try to
link to SDL SDL_INCLUDE_DIR, where to find SDL.h

This module responds to the the flag: SDL_BUILDING_LIBRARY If
this is defined, then no SDL_main will be linked in because
only applications need main(). Otherwise, it is assumed you are
building an application and this module will attempt to locate
and set the the proper link flags as part of the returned
SDL_LIBRARY variable.

Don't forget to include SDLmain.h and SDLmain.m your project for
the OS X framework based version. (Other versions link to
-lSDLmain which this module will try to find on your behalf.)
Also for OS X, this module will automatically add the -frame‐
work Cocoa on your behalf.

Additional Note: If you see an empty SDL_LIBRARY_TEMP in your
configuration and no SDL_LIBRARY, it means CMake did not find
your SDL library (SDL.dll, libsdl.so, SDL.framework, etc). Set
SDL_LIBRARY_TEMP to point to your SDL library, and configure
again. Similarly, if you see an empty SDLMAIN_LIBRARY, you
should set this value as appropriate. These values are used to
generate the final SDL_LIBRARY variable, but when these values
are unset, SDL_LIBRARY does not get created.

$SDLDIR is an environment variable that would correspond to the
./configure --prefix=$SDLDIR used in building SDL. l.e.galup
9-20-02

Modified by Eric Wing. Added code to assist with automated
building by using environmental variables and providing a more
controlled/consistent search behavior. Added new modifications
to recognize OS X frameworks and additional Unix paths (Free‐
BSD, etc). Also corrected the header search path to follow
"proper" SDL guidelines. Added a search for SDLmain which is
needed by some platforms. Added a search for threads which is
needed by some platforms. Added needed compile switches for
MinGW.

On OSX, this will prefer the Framework version (if found) over
others. People will have to manually change the cache values of
SDL_LIBRARY to override this selection or set the CMake environ‐
ment CMAKE_INCLUDE_PATH to modify the search paths.

Note that the header path has changed from SDL/SDL.h to just
SDL.h This needed to change because "proper" SDL convention is
#include "SDL.h", not <SDL/SDL.h>. This is done for portability
reasons because not all systems place things in SDL/ (see Free‐
BSD).

FindSDL_image

Locate SDL_image library This module defines SDLIMAGE_LIBRARY,
the name of the library to link against SDLIMAGE_FOUND, if
false, do not try to link to SDL SDLIMAGE_INCLUDE_DIR, where to
find SDL/SDL.h

$SDLDIR is an environment variable that would correspond to the

module, but with modifications to recognize OS X frameworks and
additional Unix paths (FreeBSD, etc).

FindSDL_mixer

Locate SDL_mixer library This module defines SDLMIXER_LIBRARY,
the name of the library to link against SDLMIXER_FOUND, if
false, do not try to link to SDL SDLMIXER_INCLUDE_DIR, where to
find SDL/SDL.h

$SDLDIR is an environment variable that would correspond to the
./configure --prefix=$SDLDIR used in building SDL.

Created by Eric Wing. This was influenced by the FindSDL.cmake
module, but with modifications to recognize OS X frameworks and
additional Unix paths (FreeBSD, etc).

FindSDL_net

Locate SDL_net library This module defines SDLNET_LIBRARY, the
name of the library to link against SDLNET_FOUND, if false, do
not try to link against SDLNET_INCLUDE_DIR, where to find the
headers

$SDLDIR is an environment variable that would correspond to the
./configure --prefix=$SDLDIR used in building SDL.

module, but with modifications to recognize OS X frameworks and
additional Unix paths (FreeBSD, etc).

FindSDL_sound

Locates the SDL_sound library

FindSDL_ttf

Locate SDL_ttf library This module defines SDLTTF_LIBRARY, the
name of the library to link against SDLTTF_FOUND, if false, do
not try to link to SDL SDLTTF_INCLUDE_DIR, where to find
SDL/SDL.h

$SDLDIR is an environment variable that would correspond to the
./configure --prefix=$SDLDIR used in building SDL.

Created by Eric Wing. This was influenced by the FindSDL.cmake
module, but with modifications to recognize OS X frameworks and
additional Unix paths (FreeBSD, etc).

FindSWIG
Find SWIG

This module finds an installed SWIG. It sets the following
variables:

SWIG_FOUND - set to true if SWIG is found
SWIG_DIR - the directory where swig is installed
SWIG_EXECUTABLE - the path to the swig executable
SWIG_VERSION - the version number of the swig executable

All informations are collected from the SWIG_EXECUTABLE so the
version to be found can be changed from the command line by
means of setting SWIG_EXECUTABLE

FindSelfPackers
Find upx

This module looks for some executable packers (i.e. softwares
that compress executables or shared libs into on-the-fly
self-extracting executables or shared libs. Examples:

UPX: http://wildsau.idv.uni-linz.ac.at/mfx/upx.html

SQUISH_INSTALL_DIR_FOUND Was the install directory found?
SQUISH_SERVER_EXECUTABLE_FOUND Was the server executable found?
SQUISH_CLIENT_EXECUTABLE_FOUND Was the client executable found?

macro SQUISH_ADD_TEST(testName applicationUnderTest testSuite
testCase)

ENABLE_TESTING()
FIND_PACKAGE(Squish)
IF (SQUISH_FOUND)
SQUISH_ADD_TEST(myTestName myApplication testSuiteName testCaseName)
ENDIF (SQUISH_FOUND)

FindSubversion
Extract information from a subversion working copy

The module defines the following variables:

Subversion_SVN_EXECUTABLE - path to svn command line client
Subversion_VERSION_SVN - version of svn command line client
Subversion_FOUND - true if the command line client was found

If the command line client executable is found the macro

Subversion_WC_INFO(<dir> <var-prefix>)

is defined to extract information of a subversion working copy
at a given location. The macro defines the following variables:

<var-prefix>_WC_URL - url of the repository (at <dir>)
<var-prefix>_WC_ROOT - root url of the repository
<var-prefix>_WC_REVISION - current revision
<var-prefix>_WC_LAST_CHANGED_AUTHOR - author of last commit
<var-prefix>_WC_LAST_CHANGED_DATE - date of last commit
<var-prefix>_WC_LAST_CHANGED_REV - revision of last commit
<var-prefix>_WC_LAST_CHANGED_LOG - last log of base revision
<var-prefix>_WC_INFO - output of command `svn info <dir>'

Example usage:

FIND_PACKAGE(Subversion)
IF(Subversion_FOUND)
Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project)
MESSAGE("Current revision is ${Project_WC_REVISION}")
Subversion_WC_LOG(${PROJECT_SOURCE_DIR} Project)
MESSAGE("Last changed log is ${Project_LAST_CHANGED_LOG}")
ENDIF(Subversion_FOUND)

FindTCL
TK_INTERNAL_PATH was removed.

This module finds if Tcl is installed and determines where the
include files and libraries are. It also determines what the
name of the library is. This code sets the following variables:

TCL_FOUND = Tcl was found
TK_FOUND = Tk was found
TCLTK_FOUND = Tcl and Tk were found
TCL_LIBRARY = path to Tcl library (tcl tcl80)
TCL_INCLUDE_PATH = path to where tcl.h can be found
TCL_TCLSH = path to tclsh binary (tcl tcl80)
TK_LIBRARY = path to Tk library (tk tk80 etc)
TK_INCLUDE_PATH = path to where tk.h can be found
TK_WISH = full path to the wish executable

In an effort to remove some clutter and clear up some issues for
people who are not necessarily Tcl/Tk gurus/developpers, some
variables were moved or removed. Changes compared to CMake 2.4
are:

=> they were only useful for people writing Tcl/Tk extensions.
=> these libs are not packaged by default with Tcl/Tk distributions.
Even when Tcl/Tk is built from source, several flavors of debug libs
are created and there is no real reason to pick a single one
specifically (say, amongst tcl84g, tcl84gs, or tcl84sgx).
Let's leave that choice to the user by allowing him to assign
TCL_LIBRARY to any Tcl library, debug or not.
=> this ended up being only a Win32 variable, and there is a lot of
confusion regarding the location of this file in an installed Tcl/Tk
tree anyway (see 8.5 for example). If you need the internal path at
this point it is safer you ask directly where the *source* tree is
and dig from there.

FindTIFF
Find TIFF library

Find the native TIFF includes and library This module defines

TIFF_INCLUDE_DIR, where to find tiff.h, etc.
TIFF_LIBRARIES, libraries to link against to use TIFF.
TIFF_FOUND, If false, do not try to use TIFF.

also defined, but not for general use are

TIFF_LIBRARY, where to find the TIFF library.

FindTclStub
TCL_STUB_LIBRARY_DEBUG and TK_STUB_LIBRARY_DEBUG were removed.

This module finds Tcl stub libraries. It first finds Tcl include
files and libraries by calling FindTCL.cmake. How to Use the Tcl
Stubs Library:

http://tcl.activestate.com/doc/howto/stubs.html

Using Stub Libraries:

http://safari.oreilly.com/0130385603/ch48lev1sec3

This code sets the following variables:

TCL_STUB_LIBRARY = path to Tcl stub library
TK_STUB_LIBRARY = path to Tk stub library
TTK_STUB_LIBRARY = path to ttk stub library

In an effort to remove some clutter and clear up some issues for
people who are not necessarily Tcl/Tk gurus/developpers, some
variables were moved or removed. Changes compared to CMake 2.4
are:

=> these libs are not packaged by default with Tcl/Tk distributions.
Even when Tcl/Tk is built from source, several flavors of debug libs
are created and there is no real reason to pick a single one
specifically (say, amongst tclstub84g, tclstub84gs, or tclstub84sgx).
Let's leave that choice to the user by allowing him to assign
TCL_STUB_LIBRARY to any Tcl library, debug or not.

FindTclsh
Find tclsh

This module finds if TCL is installed and determines where the
include files and libraries are. It also determines what the
name of the library is. This code sets the following variables:

TCLSH_FOUND = TRUE if tclsh has been found
TCL_TCLSH = the path to the tclsh executable

In cygwin, look for the cygwin version first. Don't look for it
later to avoid finding the cygwin version on a Win32 build.

FindThreads
This module determines the thread library of the system.

The following variables are set

CMAKE_THREAD_LIBS_INIT - the thread library
CMAKE_USE_SPROC_INIT - are we using sproc?
CMAKE_USE_WIN32_THREADS_INIT - using WIN32 threads?
CMAKE_USE_PTHREADS_INIT - are we using pthreads
CMAKE_HP_PTHREADS_INIT - are we using hp pthreads

FindUnixCommands
Find unix commands from cygwin

This module looks for some usual Unix commands.

FindVTK
Find a VTK installation or build tree.

The following variables are set if VTK is found. If VTK is not
found, VTK_FOUND is set to false.

VTK_FOUND - Set to true when VTK is found.
VTK_USE_FILE - CMake file to use VTK.
VTK_MAJOR_VERSION - The VTK major version number.
VTK_MINOR_VERSION - The VTK minor version number
(odd non-release).
VTK_BUILD_VERSION - The VTK patch level
(meaningless for odd minor).
VTK_INCLUDE_DIRS - Include directories for VTK
VTK_LIBRARY_DIRS - Link directories for VTK libraries
VTK_KITS - List of VTK kits, in CAPS
(COMMON,IO,) etc.
VTK_LANGUAGES - List of wrapped languages, in CAPS
(TCL, PYHTON,) etc.

The following cache entries must be set by the user to locate
VTK:

VTK_DIR - The directory containing VTKConfig.cmake.
This is either the root of the build tree,
or the lib/vtk directory. This is the
only cache entry.

The following variables are set for backward compatibility and
should not be used in new code:

USE_VTK_FILE - The full path to the UseVTK.cmake file.
This is provided for backward
compatibility. Use VTK_USE_FILE
instead.

FindWget
Find wget

This module looks for wget. This module defines the following
values:

WGET_EXECUTABLE: the full path to the wget tool.
WGET_FOUND: True if wget has been found.

FindWish
Find wish installation

This module finds if TCL is installed and determines where the
include files and libraries are. It also determines what the
name of the library is. This code sets the following variables:

TK_WISH = the path to the wish executable

if UNIX is defined, then it will look for the cygwin version
first

FindXMLRPC
Find xmlrpc

Find the native XMLRPC headers and libraries.

XMLRPC_INCLUDE_DIRS - where to find xmlrpc.h, etc.
XMLRPC_LIBRARIES - List of libraries when using xmlrpc.
XMLRPC_FOUND - True if xmlrpc found.

XMLRPC modules may be specified as components for this find mod‐
ule. Modules may be listed by running "xmlrpc-c-config". Mod‐
ules include:

c++ C++ wrapper code
libwww-client libwww-based client
cgi-server CGI-based server
abyss-server ABYSS-based server

Typical usage:

FIND_PACKAGE(XMLRPC REQUIRED libwww-client)

FindZLIB
Find zlib

Find the native ZLIB includes and library

ZLIB_INCLUDE_DIRS - where to find zlib.h, etc.
ZLIB_LIBRARIES - List of libraries when using zlib.
ZLIB_FOUND - True if zlib found.

Findosg

NOTE: It is highly recommended that you use the new FindOpen‐
SceneGraph.cmake introduced in CMake 2.6.3 and not use this Find
module directly.

This is part of the Findosg* suite used to find OpenSceneGraph
components. Each component is separate and you must opt in to
each module. You must also opt into OpenGL and OpenThreads (and
Producer if needed) as these modules won't do it for you. This
is to allow you control over your own system piece by piece in
case you need to opt out of certain components or change the
Find behavior for a particular module (perhaps because the
default FindOpenGL.cmake module doesn't work with your system as
an example). If you want to use a more convenient module that
includes everything, use the FindOpenSceneGraph.cmake instead of
the Findosg*.cmake modules.

Locate osg This module defines

OSG_FOUND - Was the Osg found? OSG_INCLUDE_DIR - Where to find
the headers OSG_LIBRARIES - The libraries to link against for
the OSG (use this)

OSG_LIBRARY - The OSG library OSG_LIBRARY_DEBUG - The OSG debug
library
