dnl Synopsis:
dnl AC_PATH_GL
dnl Purpose:
dnl To seek and find your Qt installation
dnl Access:
dnl
dnl --with-gl-dir where the root of gl is installed (/usr/local/gl)
dnl --with-gl-include where the gl includes are. (/usr/local/gl/include)
dnl --with-gl-lib where the gl library is installed. (/usr/local/gl/lib)
dnl --enable-mesagl If you always want MesaGL instead of just GL
dnl Defines: (to DEFS or config.h)
dnl None
dnl Substitutions: (to Makefile from Makefile.in)
dnl GL_CFLAGS - Path to GL includes (-Iwhateverincdir)
dnl GL_LIBS - Linkpath and libraryname (-Lwhateverlibdir -lgl)
dnl Requirements:
dnl AC_PATH_XTRA must be called first, for now
dnl Returns:
dnl values in GL_CFLAGS and GL_LIBS, or configure will stop on error
