For meson you just need to to "pip install meson ninja" in your python
distro and you should be good to go (they will be installed in python's
Scripts directory). Don't use chocolatey to install meson/ninja - I ran
into issues doing that.

AFAICT meson will use whatever version of VC you have installed,
although I have only been testing with VC2019.
