You can try to add this to the cmake command line to force them to be found: -DQWT_LIBRARIES=/usr/local/lib64/libqwt.so -DQWT_INCLUDE_DIRS=/usr/local/include (I'm assuming that's the correct include path based on your library path.) > At the moment, I think I will hold off on installing PyQwt since it is > unnecessary per Tom, and I do not need it. > Yes, don't worry about that. Final thought. Have you tried to install GNU Radio using PyBOMBS? I know the original PyBOMBS worked fine on older RedHat installations, though I'm not positive that anyone's tried the new version on it.
