Well, your request is still underspecified, so the response filled in
one possible answer.  In this case: you want it to find the
fully-qualified path, but you didn't say whether you wanted it to do
that every time (what if it changes between runs!) or only do so the
first time in a build directory and then cache it after that.  Or
maybe cache it as long as the cached path is still present?  Some
other criteria for deciding to not do the work of searching the entire
filesystem?
