A lightweight game engine written in modern C++

Is it possible to build this for Windows on Linux? That's one of the things that would make it stand out for me. I'm finding myself using Windows less and less, but I realize that most users are on Windows.

I've had some success building things using the MinGW GCC toolchain on Linux, but I'm not sure if all the regular MinGW libraries are available, so the engine might have to submodule or fetch dependencies.
