For me, it's barely a context switch, sync the repo and run "meson test" (or cmake) there. I haven't tried the shared folder yet. Testing the windows build is not something you can really do on Linux... So I will prefer a native build whenever possible. Anyway, no need to convince me about the need for cross-compilers :) However, I regret that we have undermaintained and duplicated mingw*-pkg.

I imagine with use of container/namespaces, the target Fedora sys-root could be simply mounted in a well-known location (instead of duplicating packages, or developing a rpm multi-arch solution) -- Marc-André Lureau
