1008 dnl All of the libraries that are found (since "-lglut" or "-lGLX" might

1010 dnl with any other libraries that are necessary to successfully link an
1011 dnl OpenGL application (e.g. the X11 libraries). Care has been taken to
1012 dnl make sure that all of the libraries in "GL_LIBS" are listed in the

1020 dnl also set to either "yes" or "no" (depending on which libraries were
