> The obvious: CMake compiles into either Makefiles or Visual Studio solutions, allowing for cross Linux / Windows builds. I get that this is especially attractive for some companies earning money with Windows. But how important are contributions from developers on Windows for Linux distributions and the free software community? I think that most companies which use open source libraries on Windows are unlikely to give anything back. Also, when it comes to things like networking and server software, Windows has many important differences, and is not that relevant at all any more. Well, every project will need to figure out on its own whether supporting Windows builds is worth the time and hassle.
