CI: pango build problems on Windows
Just to track things:
- gtk master needs pango 1.44
- CI uses msys2 which only has pango 1.43
- The package in msys2 can't be upgraded to 1.44 because rendering is broken on Windows
- With meson we can build pango as a subproject, but that is broken too (either a meson or toolchain bug), we had the same error a year ago..: the linker fails when trying to link the subproject libpango into gtk.
Possible solutions:
- Provide a pango 1.44 msys2 package and download/install it in CI
- Figure out what makes pango so special to make linking fail (I tried that a year ago already afair)
