I had the same idea, but went with the directory property first.
The target property would avoid any scope-issues, it looks quite elegant.

I haven't worked on the link-dependency-calculation much, so I wasn't sure how 
this code exactly works, so I went with the (for me) easier way, checking 
directly in FindTargetToUse().

Can you give me a pointer where the member of the link interface are checked ?
