How to integrate openNI in Qt in Ubuntu?

Question

Currently I am making a project on recognizing human actions using Kinect. Since I work in Ubuntu and I need the skeleton information, I choose openNI and NITE. I want to use Qt to create a GUI application, but I don't know how to integrate openNI in Qt. All the samples of openNI and NITE run well, but I failed to build any of them in Qt creator. I really hope anyone can help me on this(Say how to build NiUserTracker in Qt creator). I will also apriciate it if anyone can give some sample Qt projects.

I have tried to build NiUserTracker in Qt creator: Content of .pro file:

I have added the inlcude path of openNI and libs, however when I built the program, it shows:

I guess it is because the glut libs are not included. However both libs are .lib files, which seems cannot be added in Qt creator....

Thank you very much!

If you don't show any details of what "fails to build" actually means, how do you expect anyone to help you fix those? Please describe exactly what you did to try and integrate them, and the exact error messages you're seeing. — Mat
You're adding a bunch of libraries already in your .pro file. Why aren't you adding the OpenGL ones too, in the same fashion? — Mat
Do you mean glut32.lib and glut64.lib? It seems they cannot be added in Qt creator in the same fashion.. It seems becasue they are not .so files.. — eaglesky

did you tried to use openNI with openCV + qt support? another soluction is this.
