My experience is very much the same.

I had problems with FindVSXU.cmake; I cry your pardon if you already 
resolved these. First, it searches for vsxu_platform.h and I believe 
that should be vsx_platform.h . Second, my includes/vsxu directory has 
subdirectories in it, so e.g. "#include <vsx_manager.h>" causes a 
compilation error, because the header is not *directly* in the directory 
found by CMake.

After I compiled, I get a black square when something is playing. FWIW, 
I'm using nVidia proprietary drivers.
