It clearly doesn't have the full automation stuff, but appears to have the parts about building the postgres dependency.
Yeah, that's essentially the manual process, though I haven't tested it in a while. The Ansible stuff is not currently public. I suspect (or rather, hope) that we can pull in all the additional packages required using Chocolatey which shouldn't be too onerous.
Probably my main concern is that the Meson build can use the same version of the VC++ compiler that we use (v14), which is carefully matched for compatibility with all the various components, just in case anything passes CRT pointers around. Python is the one thing we don't build ourselves on Windows and the process will build modules like gssapi and psycopg (which links with libpq of course), so we're basically following what they use.
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.
OK, that sounds easy enough then (famous last words!)
