get_filename_component | |
---------------------- | |
Get a specific component of a full filename. | |
------------------------------------------------------------------------------ | |
:: | |
get_filename_component(<VAR> <FileName> <COMP> [CACHE]) | |
Set ``<VAR>`` to a component of ``<FileName>``, where ``<COMP>`` is one of: | |
:: | |
DIRECTORY = Directory without file name | |
NAME = File name without directory | |
EXT = File name longest extension (.b.c from d/a.b.c) | |
NAME_WE = File name without directory or longest extension | |
PATH = Legacy alias for DIRECTORY (use for CMake <= 2.8.11) | |
Paths are returned with forward slashes and have no trailing slashes. | |
The longest file extension is always considered. If the optional | |
``CACHE`` argument is specified, the result variable is added to the | |
cache. | |
------------------------------------------------------------------------------ | |
:: | |
get_filename_component(<VAR> <FileName> | |
<COMP> [BASE_DIR <BASE_DIR>] | |
[CACHE]) | |
Set ``<VAR>`` to the absolute path of ``<FileName>``, where ``<COMP>`` is one | |
of: | |
:: | |
ABSOLUTE = Full path to file | |
REALPATH = Full path to existing file with symlinks resolved | |
If the provided ``<FileName>`` is a relative path, it is evaluated relative | |
to the given base directory ``<BASE_DIR>``. If no base directory is | |
provided, the default base directory will be | |
:variable:`CMAKE_CURRENT_SOURCE_DIR`. | |
Paths are returned with forward slashes and have no trailing slahes. If the | |
optional ``CACHE`` argument is specified, the result variable is added to the | |
cache. | |

:: | |
get_filename_component(<VAR> <FileName> | |
PROGRAM [PROGRAM_ARGS <ARG_VAR>] | |
[CACHE]) | |
The program in ``<FileName>`` will be found in the system search path or | |
left as a full path. If ``PROGRAM_ARGS`` is present with ``PROGRAM``, then | |
any command-line arguments present in the ``<FileName>`` string are split | |
from the program name and stored in ``<ARG_VAR>``. This is used to | |
separate a program name from its arguments in a command line string. |
