Subject: [PATCH] Fixed include order issue.  The cuda utils headers weren't
 including dlib/config.h before the asserts that DLIB_USE_CUDA must be
 defined.  This only matters for users who try to install dlib and use some
 build system that doesn't define DLIB_USE_CUDA, and so therefore need
 dlib/config.h to define it for them.
