I am not really following what you mean with the cmake bit here?
You can configure additional places to search for cmake files with meson setup --cmake-prefix-path=...
None of the dependencies include cmake files for distribution on Windows, so there are no additional files to tell meson to search for. The same applies to pkgconfig files, which is why the EDB team had to manually craft them.

Yes, and?
And that's why we really need to be able to locate headers and libraries easily by passing paths to meson, as we can't rely on pkgconfig, cmake, or things being in some standard directory on Windows.
