Check for GLU. If GLU is found, the required preprocessor and linker flags are included in the output variables "GLU_CFLAGS" and "GLU_LIBS", respectively. This macro adds the configure option "--with-apple-opengl-framework", which users can use to indicate that Apple's OpenGL framework should be used on Mac OS X. If Apple's OpenGL framework is used, the symbol "HAVE_APPLE_OPENGL_FRAMEWORK" is defined. If no GLU implementation is found, "no_glu" is set to "yes".
