Description

In various specific circumstances (not always) ctest fails if python 3 is being used.

For example it fails on windows; it fails if you specify PYTHON_EXECUTABLE=/usr/bin/python3 specifically for cmake.

Some of this is due to python 2 specific code that has snuck into the test code, and some is due to calling subsidiary python scripts using the wrong python interpreter.
