I'm still slightly bothered by the build options inconsistency between
autotools: reuse --with-platform=drm
meson: new -D platform=display
I'd be happy with either one being used everywhere, but from what you
said last time I think you'd prefer to reuse `platform=drm`; can we
drop the meson hunks above and use `with_platform_drm` in
src/vulkan/wsi/meson.build?
I know this is a bit of a nit-pick, but I still wanted to mention it (:
