Subject: CMakeAddFortranSubdirectory: Allow full paths to directories

Fix the implementation to allow full paths with spaces.  Change the
interpretation of relative paths to be with respect to the current binary
directory.  This matches the convention used in ExternalProject.  Test
both full and relative paths in the VSGNUFortran test.
