title: Qt version is invalid
body: <p>I am working on Linux and I have installed Qt Creator 2.5.2, Qt libraries 4.7.4 and 4.4.3 all from sources. I cannot install the binaries directly for incompatibility between versions. The installation processes for both Qt 4.7.4 and Qt 4.4.3 were the same. The issue I am facing is that Qt Creator recognizes Qt 4.7.4 but not Qt 4.4.3, with the error</p>
  
  <blockquote>
    <p>The Qt version is invalid : Could not determine the path to the
    binaries of the Qt installation, maybe the path is wrong.</p>
  </blockquote>
  
  <p>Well each library is installed in <code>/home/$username/qt/Qt-$version</code>. When I manually compile a project with</p>
  
  <pre><code>cd directory
  /home/$username/qt/Qt-4.4.3/qmake $PATHPRO
  make
  </code></pre>
  
  <p>Everything work as a charm and I can run the app.</p>
  
  <p>What did I tried?</p>
  
  <ul>
  <li>Recompile Qt-4.4.3</li>
  <li>Check the folder permissions</li>
  <li>Restart Qt Creator</li>
  <li>Smash my head on my desktop</li>
  </ul>
  
  <p>Any thoughts? The OS is SUSE Enterprise 11-32bits.</p>
