compiling Openscenegraph 3.1.8 with Qt 5.0.2

Question

I'm trying to compile openscenegraph-3.1.8 with Qt 5.0.2 using mingw-32 compiler after configuring with cmake 2.8.11 on windows 7 (basic).

But, in the compilation process i got the following errors :-

Looks like you are building QT against OpenGL 2 and OSG with a different version - see link for rebuilding QT: http://www.qtforum.org/article/39175/opengl-with-qt-5-0-1-and-glew.html
