That's a very good point - using the command override approach, the
CMAKE_CURRENT_SOURCE_DIR is always the directory of the target in
question, and looking at our current code I see we do make use of that
assumption.  We would need a way to find out what
CMAKE_CURRENT_SOURCE_DIR was when the target was defined if we're
going to build up a list after the fact - maybe something like
get_target_property(TDIR <targetname> SOURCE_DIR) to get the source
directory in which the target was defined.  In combination with the
SOURCES property it would allow for full path reconstruction.
