I am trying to build OpenCV 2.4.1 with OpenGL support, and it keeps faling. I have OpenGL installed in my Ubuntu 11.04, libs are under /usr/lib/libGL.so as usual. I know my OpenGL installation is correct because I have C++ OpenGL projects that compile, link and run OK.
I run the cmake command as follows, because I want both CUDA and OpenGL support.
/data/OpenCV-2.4.1/build $ cmake -D WITH_OPENGL=ON -D CMAKE_BUILD_TYPE=RELEASE -D WITH_CUDA=ON -D CUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda/ -D BUILD_EXAMPLES=ON -D WITH_TBB=ON ..
This is the output I get from this, telling me CUDA was properly detected, but OpenGL wasn't
