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.
