Windows development using CMake

[kosumosu]

Is your feature request related to a problem? Please describe.
Windows development is now only possible using Visual Studio. There's much better options like CLion for example. But currently CMake is only properly working on linux.

Describe the solution you'd like
I would suggest to move fully to CMake, even on Windows, because it will allow developers to choose IDE's they like. Who want to stay with VS - can still generate VS project for themselves.

Now I have to manually tune CMakeLists.txt to open in CLion without errors.

Just a side note:
I also thing SDL include path is not set anywhere in CMakeLists.txt, it's only luck that it works on linux.

I fully agree on this, we plan to move to CMake on Windows, and @Masterkatze is currently working on it.

I agree with this suggestion, Clion is an excellent tool
