   In the long run this is a terrible way to indicate this and needs to be changed. It is inconsistent with how we do everything else by simply adding additional supports using --with-xxx.    We should have --with-cuda for basic cuda support and --with-cusp for cusp support (which may automatically add the --with-cuda).
