Subject: [PATCH] fxlink: find SDL2 without -mwindows to stay in console
 [Windows]

When loading SDL2 with pkg-config the -mwindows flag is added, which
instructs the loader to load the program through WinMain() and not
create a console for it. This is intended for GUI programs. However,
fxlink is a CLI program with just occasionally an SDL window on top of
it. Disable -mwindows to keep the console and terminal output. I don't
know how to do that with the pkg-config CMake module, so use the SDL2
module for the Windows build instead.
