Hi Thomas, Just to take a step back, if you need to change the Python that CMake finds, the relevant CMake variables are (with example values):
-DPYTHON_EXECUTABLE=/usr/bin/python3 -DPYTHON_INCLUDE_DIR=/usr/include/python3.5m -DPYTHON_LIBRARY=/usr/lib64/ libpython3.5m.so Regarding your question, you'll need to post the output from running cmake in a clean directory. And the result of running "grep PYTHON CMakeCache.txt".
