Check for GLUT. If GLUT is found, the required compiler and linker flags are included in the output variables "GLUT_CFLAGS" and "GLUT_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 GLUT is not found, "no_glut" is set to "yes".
