On macOS, a Python interpreter that is embedded in a C++ process doesn't use the virtual environment that the configured Python executable belongs to, even if that environment is activated: CPython takes the running binary as the executable and never finds the pyvenv.cfg of the environment. On Linux, it finds `python3` in the PATH instead. Therefore, C++ tutorials that embed Python, don't find Python modules that are only installed in the virtual environment, even though CMake found them with the Python executable of that environment and enabled the tutorials. Set PYTHONEXECUTABLE to the configured Python executable for the tutorials on macOS, which makes the embedded interpreter use the same environment. (cherry picked from commit a3f3920)
Like 9ac24d5 but for the SOFIE tests that are only in ROOT 6.40.
