875 dnl OpenGL) before a vendor's version of OpenGL, unless we were

882 dnl All of the libraries that are found (since "-lglut" or "-lGLX" might
883 dnl be missing) are added to the shell output variable "GL_LIBS", along
884 dnl with any other libraries that are necessary to successfully link an
885 dnl OpenGL application (e.g. the X11 libraries). Care has been taken to
886 dnl make sure that all of the libraries in "GL_LIBS" are listed in the
889 dnl Additionally, the shell output variable "GL_CFLAGS" is set to any

894 dnl also set to either "yes" or "no" (depending on which libraries were
