55efe08bdf chore: explicitly link SDL2 
TODO: What happens on Windows? macOS?

78922b64ea fix: vcpkg stores SDL.h under SDL2 folder 
macOS and Linux seem to not, so in order to get CI working again I
should make use of the preprocessor.

FIXME: I think this makes vcpkg a **hard** requirement which perhaps
isn't ideal if I want ZBA to be as easy to build as possible. I should
try ensuring that building w/out vcpkg works as well
