It shows up in CMakeSetup as SDL_LIBRARY_TEMP-NOTFOUND.  Leaving it alone doesn't seem to cause a problem, but to the user it looks like an error.  If FindSDL is creating this variable, shouldn't it initialize it or something?

Yep, that is a bug, most likely from a FIND_* call putting it in the cache.
You can create a bug entry.
