cmakecompat(1) General Commands Manual cmakecompat(1)
NAME
cmakecompat - Reference of CMake compatibility commands.
COMPATIBILITY COMMANDS
CMake Compatibility Listfile Commands - Obsolete commands supported by CMake for compatibility.
This is the documentation for now obsolete listfile commands from previous CMake versions, which are still supported for compatibility rea-
sons. You should instead use the newer, faster and shinier new commands. ;-)
build_name
Deprecated. Use ${CMAKE_SYSTEM} and ${CMAKE_CXX_COMPILER} instead.
build_name(variable)
Sets the specified variable to a string representing the platform 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 CMakeList.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 arguments 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 output. To capture
the return value of the execution, provide a RETURN_VALUE. If OUTPUT_VARIABLE is specified, then no output will go to the std-
out/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 command.
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 number 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 command. 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 extension into the given directory. Only files existing in the current
source tree or its corresponding location in the binary tree may be listed. If a file specified already has an extension, 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 directory. The directory <dir> is relative to the installation prefix,
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 targets (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 automatically
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 PREORDER 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 make-
files or projects for a set of examples in a project. You would want CMake to generate makefiles or project files for all the exam-
ples 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 distribution, 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 utility_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.
