title: Issues when merging a C++ project with a Qt project
body: <p>This project is a MVC using Qt (and OpenGl) in the View part and Boost Graph library in the Controler part. </p>
  
  <p>I have Developed the model and the view part on Eclipse CDT, and it successfully compile and run. The view part is developed under QtCreator, the window compile and run successfuly too.</p>
  
  <p>But when i add the model and the controller files in the Qt project i have some compilation issues.</p>
  
  <p>I'm on Mac OSX Mavericks, Boost 1.55.0, Qt 5.2.1 (lastest version of Qt creator)</p>
  
  <p>Here is the compilation output :</p>
  
  <pre><code>MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk -mmacosx-version-min=10.6 -Wall -W -fPIE -DQT_QML_DEBUG -DQT_DECLARATIVE_DEBUG -DQT_OPENGL_LIB -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I../../../../../Qt/5.2.1/clang_64/mkspecs/macx-clang -I../IBirdCVGui -I&lt;/Users/thomas/Documents/workspace/interface/testsQt/IBirdCVGui/boost_1_55_0/&gt; -I../../../../../Qt/5.2.1/clang_64/lib/QtOpenGL.framework/Versions/5/Headers -I../../../../../Qt/5.2.1/clang_64/lib/QtWidgets.framework/Versions/5/Headers -I../../../../../Qt/5.2.1/clang_64/lib/QtGui.framework/Versions/5/Headers -I../../../../../Qt/5.2.1/clang_64/lib/QtCore.framework/Versions/5/Headers -I. -I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/System/Library/Frameworks/OpenGL.framework/Versions/A/Headers -I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/System/Library/Frameworks/AGL.framework/Headers -I. -F/Users/thomas/Qt/5.2.1/clang_64/lib -o main.o ../IBirdCVGui/main.cpp

  <p>I looked in The file Qt/5.2.1/clang_64/lib/QtOpenGL.framework/Versions/5/Headers, and the output of my ls is:</p>
  
  <pre><code>(Canopy 32bit) rivesaltes:Headers thomas$ ls

  <p>There is like 10 .h files and 10 .cpp files in my project, so if you want to see the code, i can post it but is there something more usefull than just post it here.</p>
  
  <p>So i have several questions:</p>
  
  <ul>
  <li>Am i missing something big here ? </li>
  <li>Why Qt open Gl is whining when i try to add some "classic" C++ code?</li>
  <li>Is boost graph library potentialy messing with Qt ?</li>
  <li>Is something to know with Qt that i missed in my tutorials?</li>
  </ul>
