Like Pascal said, clearing PYTHON_EXECUTABLE from your CMakeCache.txt
was sufficient (you do not have to wipe the full build directory). The
default /usr/bin/python interpreter is Python 2.7, but CMake will now
search for python3 first and use that if it is new enough.
A virtualenv could be used, but is not necessary.
