Hi Stephen,

If thingYYY detects SDL and uses it at configure stage, it should be
recorded in the dependency list.  I suppose this is up to the
maintainer to deal with this as whether the aforementioned feature
exists or not, nothing would prevent the user from deinstalling SDL
and break thingYYY otherwise.
