COMPATIBILITY COMMANDS
CMake Compatibility Listfile Commands - Obsolete commands supported by CMake for compatibility.
This is the documentation for now obsolete listfile commands from pre‐
vious CMake versions, which are still supported for compatibility rea‐
sons. You should instead use the newer, faster and shinier new com‐
mands. ;-)
build_name
Deprecated. Use ${CMAKE_SYSTEM} and ${CMAKE_CXX_COMPILER}
instead.
build_name(variable)
Sets the specified variable to a string representing the plat‐
form and compiler settings. These values are now available
through the CMAKE_SYSTEM and CMAKE_CXX_COMPILER variables.
exec_program
Deprecated. Use the execute_process() command instead.
Run an executable program during the processing of the CMake‐
List.txt file.
exec_program(Executable [directory in which to run]
[ARGS <arguments to executable>]
[OUTPUT_VARIABLE <var>]
[RETURN_VALUE <var>])
The executable is run in the optionally specified directory.
The executable can include arguments if it is double quoted, but
it is better to use the optional ARGS argument to specify argu‐
ments to the program. This is because cmake will then be able
to escape spaces in the executable path. An optional argument
OUTPUT_VARIABLE specifies a variable in which to store the out‐
put. To capture the return value of the execution, provide a
RETURN_VALUE. If OUTPUT_VARIABLE is specified, then no output
will go to the stdout/stderr of the console running cmake.
export_library_dependencies
Deprecated. Use INSTALL(EXPORT) or EXPORT command.
This command generates an old-style library dependencies file.
Projects requiring CMake 2.6 or later should not use the com‐
mand. Use instead the install(EXPORT) command to help export
targets from an installation tree and the export() command to
export targets from a build tree.
The old-style library dependencies file does not take into
account per-configuration names of libraries or the LINK_INTER‐
FACE_LIBRARIES target property.
export_library_dependencies(<file> [APPEND])
Create a file named <file> that can be included into a CMake
listfile with the INCLUDE command. The file will contain a num‐
ber of SET commands that will set all the variables needed for
library dependency information. This should be the last command
in the top level CMakeLists.txt file of the project. If the
APPEND option is specified, the SET commands will be appended to
the given file instead of replacing it.
install_files
Deprecated. Use the install(FILES ) command instead.
This command has been superceded by the install command. It is
provided for compatibility with older CMake code. The FILES
form is directly replaced by the FILES form of the install com‐
mand. The regexp form can be expressed more clearly using the
GLOB form of the file command.
install_files(<dir> extension file file ...)
Create rules to install the listed files with the given exten‐
sion into the given directory. Only files existing in the cur‐
rent source tree or its corresponding location in the binary
tree may be listed. If a file specified already has an exten‐
sion, that extension will be removed first. This is useful for
providing lists of source files such as foo.cxx when you want
the corresponding foo.h to be installed. A typical extension is
'.h'.
install_files(<dir> regexp)
Any files in the current source directory that match the regular
expression will be installed.
install_files(<dir> FILES file file ...)
Any files listed after the FILES keyword will be installed
explicitly from the names given. Full paths are allowed in this
form.
The directory <dir> is relative to the installation prefix,
which is stored in the variable CMAKE_INSTALL_PREFIX.
install_programs
Deprecated. Use the install(PROGRAMS ) command instead.
This command has been superceded by the install command. It is
provided for compatibility with older CMake code. The FILES
form is directly replaced by the PROGRAMS form of the INSTALL
command. The regexp form can be expressed more clearly using
the GLOB form of the FILE command.
install_programs(<dir> file1 file2 [file3 ...])
install_programs(<dir> FILES file1 [file2 ...])
Create rules to install the listed programs into the given
directory. Use the FILES argument to guarantee that the file
list version of the command will be used even when there is only
one argument.
install_programs(<dir> regexp)
In the second form any program in the current source directory
that matches the regular expression will be installed.
This command is intended to install programs that are not built
by cmake, such as shell scripts. See the TARGETS form of the
INSTALL command to create installation rules for targets built
by cmake.
The directory <dir> is relative to the installation prefix,
which is stored in the variable CMAKE_INSTALL_PREFIX.
install_targets
Deprecated. Use the install(TARGETS ) command instead.
This command has been superceded by the install command. It is
provided for compatibility with older CMake code.
install_targets(<dir> [RUNTIME_DIRECTORY dir] target target)
Create rules to install the listed targets into the given direc‐
tory. The directory <dir> is relative to the installation pre‐
fix, which is stored in the variable CMAKE_INSTALL_PREFIX. If
RUNTIME_DIRECTORY is specified, then on systems with special
runtime files (Windows DLL), the files will be copied to that
directory.
link_libraries
Deprecated. Use the target_link_libraries() command instead.
Link libraries to all targets added later.
link_libraries(library1 <debug | optimized> library2 ...)
Specify a list of libraries to be linked into any following tar‐
gets (typically added with the add_executable or add_library
calls). This command is passed down to all subdirectories. The
debug and optimized strings may be used to indicate that the
next library listed is to be used only for that specific type of
build.
make_directory
Deprecated. Use the file(MAKE_DIRECTORY ) command instead.
make_directory(directory)
Creates the specified directory. Full paths should be given.
Any parent directories that do not exist will also be created.
Use with care.
output_required_files
Deprecated. Approximate C preprocessor dependency scanning.
This command exists only because ancient CMake versions provided
it. CMake handles preprocessor dependency scanning automati‐
cally using a more advanced scanner.
output_required_files(srcfile outputfile)
Outputs a list of all the source files that are required by the
specified srcfile. This list is written into outputfile. This is
similar to writing out the dependencies for srcfile except that
it jumps from .h files into .cxx, .c and .cpp files if possible.
remove Deprecated. Use the list(REMOVE_ITEM ) command instead.
remove(VAR VALUE VALUE ...)
Removes VALUE from the variable VAR. This is typically used to
remove entries from a vector (e.g. semicolon separated list).
VALUE is expanded.
subdir_depends
Deprecated. Does nothing.
subdir_depends(subdir dep1 dep2 ...)
Does not do anything. This command used to help projects order
parallel builds correctly. This functionality is now automatic.
subdirs
Deprecated. Use the add_subdirectory() command instead.
Add a list of subdirectories to the build.
subdirs(dir1 dir2 ...[EXCLUDE_FROM_ALL exclude_dir1 exclude_dir2 ...]
[PREORDER] )
Add a list of subdirectories to the build. The add_subdirectory
command should be used instead of subdirs although subdirs will
still work. This will cause any CMakeLists.txt files in the sub
directories to be processed by CMake. Any directories after the
PREORDER flag are traversed first by makefile builds, the PRE‐
ORDER flag has no effect on IDE projects. Any directories after
the EXCLUDE_FROM_ALL marker will not be included in the top
level makefile or project file. This is useful for having CMake
create makefiles or projects for a set of examples in a project.
You would want CMake to generate makefiles or project files for
all the examples at the same time, but you would not want them
to show up in the top level project or be built each time make
is run from the top.
use_mangled_mesa
Copy mesa headers for use in combination with system GL.
use_mangled_mesa(PATH_TO_MESA OUTPUT_DIRECTORY)
The path to mesa includes, should contain gl_mangle.h. The mesa
headers are copied to the specified output directory. This
allows mangled mesa headers to override other GL headers by
being added to the include directory path earlier.
utility_source
Specify the source tree of a third-party utility.
utility_source(cache_entry executable_name
path_to_source [file1 file2 ...])
When a third-party utility's source is included in the distribu‐
tion, this command specifies its location and name. The cache
entry will not be set unless the path_to_source and all listed
files exist. It is assumed that the source tree of the utility
will have been built before it is needed.
When cross compiling CMake will print a warning if a util‐
ity_source() command is executed, because in many cases it is
used to build an executable which is executed later on. This
doesn't work when cross compiling, since the executable can run
only on their target platform. So in this case the cache entry
has to be adjusted manually so it points to an executable which
is runnable on the build host.
variable_requires
Deprecated. Use the if() command instead.
Assert satisfaction of an option's required variables.
variable_requires(TEST_VARIABLE RESULT_VARIABLE
REQUIRED_VARIABLE1
REQUIRED_VARIABLE2 ...)
The first argument (TEST_VARIABLE) is the name of the variable
to be tested, if that variable is false nothing else is done. If
TEST_VARIABLE is true, then the next argument (RESULT_VARIABLE)
is a variable that is set to true if all the required variables
are set. The rest of the arguments are variables that must be
true or not set to NOTFOUND to avoid an error. If any are not
true, an error is reported.
write_file
Deprecated. Use the file(WRITE ) command instead.
write_file(filename "message to write"... [APPEND])
The first argument is the file name, the rest of the arguments
are messages to write. If the argument APPEND is specified, then
the message will be appended.
NOTE 1: file(WRITE ... and file(APPEND ... do exactly the same
as this one but add some more functionality.
NOTE 2: When using write_file the produced file cannot be used
as an input to CMake (CONFIGURE_FILE, source file ...) because
it will lead to an infinite loop. Use configure_file if you want
to generate input files to CMake.
