I will put this into the README of a future version:

Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/

I am also thinking about replacing the salsa20 lib with a pure python salsa implementation. This should get rid of the C++ Build Tools requirement on Windows.
