get_source_file_property
------------------------
Get a property for a source file.
::
get_source_file_property(VAR file property)
Get a property from a source file. The value of the property is
stored in the variable ``VAR``. 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
``VAR`` to "NOTFOUND", whereas inheritied properties will search the relevent
parent scope as described for the :command:`define_property` command and
if still unable to find the property, ``VAR`` will be set to an empty string.
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.
