configure tries to locate the nvidia gl library using pkg-config, but
nvidias library doesn't provide a .pc file (as far as I know, I don't
have it here).  I updated the configure script to fallback and try to
look for GL.h and libGL.so manually when pkg-config fails.  If it's
not in the default location, I think you should be able to run
configure as

  $ ./configure GL_CFLAGS=-I/opt/nvidia/include
GL_LIBS="-L/opt/nvidia/libs -lGL"

and get it to pick up the libraries from there.
