Compiling opencv2.4.9 on ubuntu14.04 WITH_QT=ON fails

edit

Hi.

My build fails when compiling opencv2.4.9 with the following cmake

cmake -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D WITH_VTK=ON ..

if I compile WITH_QT=OFF everything is fine

I Get this
