Automatically download SDL with CMake?

[icculus]

Should we use ExternalProject to either download a formal release, or clone from GitHub, so the user doesn't have to bother with this at all?

I don't know much about ExternalProject, so this might be a terrible idea.

What about CMake FetchContent? It is often cited as the current most used practice for consuming libs available on GitHub
For this kind of "Hello World" project it could be a good fit since it's quite simple to use

edit: a pull request has already been opened with FetchContent integration here : #5

I assume this issue can be closed. FetchContent is there and seems to be working.
