I think (didn't test at the moment, just browsed the cmakefiles) one case 
that still isn't handled properly, is the interaction between python/lua 
and swig. If python or lua are detected, they are enabled, and then the 
build strictly requires SWIG to be present.

I think we should check for SWIG first and require it to be present before 
automatically enabling python and lua.
