title: Error installing Qt3D with QtCreator and qt5
body: <p>I tried installing Qt3D using QtCreator 5.1.1 on Windows 8, and I can't figure out how to succeed.</p>
  
  <p>First, I followed the steps given in the documentation:</p>
  
  <ul>
  <li>get the sources on git://gitorious.org/qt/qt3d</li>
  <li>open the .pro in QtCreator</li>
  <li>add the "install" and "-j 3" arguments to the make command</li>
  </ul>
  
  <p>When I build the project, I get the following error:</p>
  
  <pre><code>    In file included from D:\qt3D\project\qt-qt3d\src\threed\global\qglnamespace.cpp:42:0:

  <p>So I created the following folders into the folder "C:\Qt\Qt5.1.1\5.1.1\mingw48_32\include":</p>
  
  <ul>
  <li>Qt3D: I copied there all .h files located into subfolders of the src/threed folder of the qt3d sources </li>
  <li>Qt3DQuick: I copied there all .h files located into the src/quick3d folder of the qt3d sources</li>
  </ul>
  
  <p>I re-run the compilation, and then I got the following errors:</p>

  <p>So, I tried to copy all needed .h file into sources folders where they are needed, but I didn't work. Moreover, I think there must be another way to get what I want, but I can't see how.</p>
  
  <p>I someone could help me, I would be glad.</p>
