I'm currently working on this. Unfortunately the necessary tools on Windows are not there yet. We use CMake to generate Makefiles or Ninja build files for Android. There isn't a reliable 'make' program on Windows that doesn't look like it was some random binary off of the internet. And currently, the generator for Ninja is producing build files where the path separator on Windows \ - is escaping characters instead of separating paths. I've put some effort into getting this addressed.
