[CMake] add_executable and WIN32 option

[Alin M Elena]

Hi,

Thanks Christian for the answer.
I think that I am a little confused about what WIN32 option does in fact.

Is WIN32 supposed to transform main() in a WinMain() entry point (transform
a /subsystem:console -> /subsystem:windows)?
Or 
WIN32 tells compiler: do not downgrade a WinMain to a main()?
