I also spent some time working on it last night, and we found that cmake was using python 2 as its python interpreter when building. After some troubleshooting, we managed to make it build cvfilter_py.so correctly by setting the PYTHON_EXECUTABLE to /usr/bin/python3 instead of /usr/bin/python. Although this seems to have fixed the issue with cmake not finding python to build cvfilter_py.so, it has not fixed the numpy import error when running cvfilter_py.so.

Running ldd on cvfilter_py.so shows that it has decided to link against libpython3.4m.so.1.0
