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.
