title: Qt4 won't compile with CMake
body: <p>I'm now under Linux with KDevelop for C++ and I want to compile a Qt4 application, but when I do, it gives me the following error :</p>
  
  <p>I compile with:</p>
  
  <pre><code>cmake -DCMAKE_INSTALL_PREFIX=/usr/local -DCMAKE_BUILD_TYPE=Debug /home/myname/projects/First Qt projet/
  </code></pre>
  
  <p>Those are the errors:</p>
  
  <pre class="lang-none prettyprint-override"><code>-- Configuring incomplete, errors occurred!
