VXL uses its own libmpeg2, correct? Well, I'm trying to get it to build libvxl_mpeg2.so instead so that it does not conflict with my system libpmeg2.so. I've been told that the current system one and the vxl one are quite different (correct me if I'm wrong) and so building against the system one does not work too well. I thought it would require a change in v3p/mpeg2/CMakeLists.txt, but that doesn't seem to make the change and it still generates a libmpeg2.so. How could I go about doing this?
