I’m on OS X, isn’t it included already?<p>Edit: I changed ‘#include &lt;GL&#x2F;glu.h&gt;’ to ‘#include &lt;OpenGL&#x2F;glu.h&gt;’ and it builds now.<p>Edit 2: Apparently it still doesn’t work:<p><pre><code>  programErrorMessage: ERROR: One or more attached shaders not successfully compiled</code></pre>
