According to FindPythonInterp.cmake, the PYTHON_ROOT_DIR variable is 
used to control the Python interpreter rather than use the normal find 
method.  I set it to the Python3 executable on my MinGW builds and it 
works as expected.  I'm guessing Linux builds would also work using this 
config method.
