cmake version 2.8.5
------------------------------------------------------------------------------
Introduction
cmake-compatcommands - 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 reasons. 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 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 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_INTERFACE_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 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 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.
