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