Make our windows builds usable from meson.
Review Request #615 — Created April 14, 2021 and submitted — Latest diff uploaded
This creates our pkg-config files on windows as well as fixes an include in pidgin.h which can cause some issues. This isn't usable as is, as you need a machine-file and a pkg-config wrapper to make this all work, but that will be updated in the win32-dev.7z file thats on data.imfreedom.org.
Compiled guifications2 (which now uses meson) on windows and verified it works.
