AX_CHECK_GLUT
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. If GLUT is not found, "no_glut" is set to "yes".
If the header "GL/glut.h" is found, "HAVE_GL_GLUT_H" is defined. If the header "GLUT/glut.h" is found, HAVE_GLUT_GLUT_H is defined. These preprocessor definitions may not be mutually exclusive.
