OpenGL and X11

[Mark Brethen]

I'm using macports to install OpenGL (mesa) since High Sierra does not have the X11 parts of it. In the Makefile there are includes and LFLAGS that need to be patched:

diff -ur cgx_2.13/src.orig/Makefile cgx_2.13/src/Makefile

This seems to work but I’m not sure it's proper.
