Hi, We use Makefiles on Linux and MacOS. Windows is not our target platform. >From what we see Linux is the fastest. We made few attempts of building our project on Windows in VS but it was very-very slow and definitely cmake generates too many project files for VS. For us it was 500+ projects in a workspace which is too much for Visual Studio. :(
