True, the semantics are a bit different, but they are dynamically linked. It's also not true that on Windows everything is a "zip files that you're supposed to unpack right in your build environment".

Also, for SDL I would recommend to use the FindSDL.cmake module (not sure whether that works with SDL2, though), and only if that fails, to resort to ExternalProject. It is good practice to offer the user the choice which way should be used through a cached variable. HTH Michael
