Synopsis
</h2>
<p class="indent" style="white-space:nowrap;">
<code>AX_CHECK_GLUT</code>
</p>
<h2>
Description
</h2>
<div class="indent">
<p>
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".
