Cannot compile QtExamples Such as "Grabber Example" in OSX Lion 10.8.2

  • I installed XCode on my MAC and Qt creator 2.6 based on QT 5.
    I Open the example project "Grabber Example", and when I compiled it I got 2337 errors/issues
    most of the errors are related to opengl libraries
    errors such as
    /Users/sina/Qt5.0.0/5.0.0/clang_64/include/QtGui/qopengl.h:88: error: OpenGL/gl.h: No such file or directory
    /Users/sina/Qt5.0.0/5.0.0/clang_64/include/QtGui/qopenglframebufferobject.h:70: error: 'GL_TEXTURE_2D' was not declared in this scope
    /Users/sina/Qt5.0.0/5.0.0/clang_64/include/QtGui/qopenglshaderprogram.h:218: error: ISO C++ forbids declaration of 'GLfloat' with no type

    In fact I do not know how I can add OpenGL libraries and include files or libraries (if one can attach few screenshots of the configuration page it would be much better) to make it compile and execute in my MAC machine.
