-dnl Search for OpenGL. We search first for Mesa (a GPL'ed version of
-dnl OpenGL) before a vendor's version of OpenGL if we were specifically
-dnl asked to with `--with-Mesa=yes' or `--with-Mesa'.
-dnl
-dnl The four "standard" OpenGL libraries are searched for: "-lGL",
-dnl "-lGLU", "-lGLX" (or "-lMesaGL", "-lMesaGLU" as the case may be) and
-dnl "-lglut".
-dnl
-dnl All of the libraries that are found (since "-lglut" or "-lGLX" might
-dnl be missing) are added to the shell output variable "GL_LIBS", along
-dnl with any other libraries that are necessary to successfully link an
-dnl OpenGL application (e.g. the X11 libraries). Care has been taken to
-dnl make sure that all of the libraries in "GL_LIBS" are listed in the
-dnl proper order.
-dnl
-dnl Additionally, the shell output variable "GL_CFLAGS" is set to any
-dnl flags (e.g. "-I" flags) that are necessary to successfully compile
-dnl an OpenGL application.
-dnl
-dnl The following shell variable (which are not output variables) are
-dnl also set to either "yes" or "no" (depending on which libraries were
-dnl found) to help you determine exactly what was found.
-dnl
-dnl have_GL
-dnl have_GLU
