get_source_file_property ------------------------ Get a property for a source file. .. code-block:: cmake get_source_file_property(<variable> <file> [DIRECTORY <dir> | TARGET_DIRECTORY <target>] <property>) Gets a property from a source file. The value of the property is stored in the specified ``<variable>``. If the source property is not found, the behavior depends on whether it has been defined to be an ``INHERITED`` property or not (see :command:`define_property`). Non-inherited properties will set ``variable`` to ``NOTFOUND``, whereas inherited properties will search the relevant parent scope as described for the :command:`define_property` command and if still unable to find the property, ``variable`` will be set to an empty string. By default, the source file's property will be read from the current source directory's scope. .. versionadded:: 3.18 Directory scope can be overridden with one of the following sub-options: ``DIRECTORY <dir>`` The source file property will be read from the ``<dir>`` directory's scope. CMake must already know about that source directory, either by having added it through a call to :command:`add_subdirectory` or ``<dir>`` being the top level source directory. Relative paths are treated as relative to the current source directory. ``TARGET_DIRECTORY <target>`` The source file property will be read from the directory scope in which ``<target>`` was created (``<target>`` must therefore already exist). Use :command:`set_source_files_properties` to set property values. Source file properties usually control how the file is built. One property that is always there is :prop_sf:`LOCATION`. See also the more general :command:`get_property` command. .. note:: The :prop_sf:`GENERATED` source file property may be globally visible. See its documentation for details.
