title: QtQuick 2.0 GL error
body: <p>I'am currently on my first QtQuick 2.0 project, but everytime I build my project, I get the following error:</p>
  
  <pre><code>cannot find -lGL
  </code></pre>
  
  <p>That's all. I think it is the <em>libglib</em> library that is missing, but I could not figure out which package I have to install to solve this problem. The QtCreator runs on my Desktop with Debian Wheezy 64bit. I do not the error when building on my Laptop running LMDE 32bit. </p>
  
  <p><strong>EDIT:</strong> Finally I could collect some more information:</p>
