Aperantly github added ninja to all of there runners now. This causes the windows build to fail. This is expected because we add the architecture as a compiler arg which is not known to ninja. Even with this the build fails. This commit disables ninja on windows for now. Once we fixed the underlying issue with ninja and windows we can reenable it.
