Thanks for the lead. I am not very advanced on this stuff so if you can direct me to an “Idiots Guide to Compiling Kicad with Microsoft Studio” if such a thing exists I’d appreciate it.

I got geographic re-annotation working in a standalone app and now I’m trying to integrate it with Kicad so I can contribute.

Hello Brian

You would still need to obtain the dependencies in some way. vcpkg
seems popular, but I still think there are issues with wxwidgets and
vcpkg and some other dependencies kicad require to enable all features
are not easily available.
