The README of libvyosconfig should contain instructions to build libvyosconfig for other platforms. Then the Python library configtree.py can be used on Windows, to serve applications that generates VyOS-configuration.
It would be great if the Docker-environment (from vyos-build) also builds libvyosconfig cross platform. Maybe using opam-cross-windows. The current build script only targets Debian.

I don't now if this is even possible, as I don't have any experience with OCaml.
My question at the forum "Build libvyosconfig for Windows?":
