AX_CHECK_GLUT
1.1 (2003/01/07) braden @ ac-archive-0.5.39
Braden McDaniel <braden@endoframe.com>
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, and the shell variable "no_glut" is set to the empty string. Also, if the header "GL/glut.h" is found, the symbol "HAVE_GL_GLUT_H" is defined; otherwise, if the header "GLUT/glut.h" is found, "HAVE_GLUT_GLUT_H" is defined. If GLUT is not found, "no_glut" is set to "yes".
