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
|
|
ABSOLUTE = Full path to file
|
|
REALPATH = Full path to existing file with symlinks resolved
|
|
PATH = Legacy alias for DIRECTORY (use for CMake <= 2.8.11)
|
|
|
|
Paths are returned with forward slashes and have no trailing slahes.
|
|
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
|
|
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.
