A cursory browse says there's no Linux-isms in the code base, so the Windows-y way to build that (without going into licensing) would be to use the Visual Studio Build Tools. They're the CLI toolchain you get for Visual Studio, but free when compiling open source projects (as of recently: https://devblogs.microsoft.com/cppblog/updates-to-visual-stu...)
They still notionally need to run on a Windows machine, although I recall people have managed to run them under wine before.
EDIT: It took me a few reads to parse what the link is saying, so: using the toolchain to compile open source dependencies is fine, even if your codebase is closed source, so long as the closed source part isn't being built with the Build Tools.
