Probably the best thing to do (on *nix at least) is, if the path is absolute,
use the given string verbatim. If the path is relative, search for the given

I think searching would be inappropriate. Just use what is given, as a
string. If the user wants a search, they can use `which`. Otherwise,
setting to a relative path reliably would be hard (and sometimes desirable).
