I forgot to mention that the PLplot project also uses CMAKE_MODULE_PATH
to find the find modules we have implemented. That use case works
without issues when CMAKE_MODULE_PATH has a blank in the full pathname.
So such a blank only appears to be an issue when CMAKE_MODULE_PATH
is used to find language support files.
