An *installed* project (what Al mentioned in his original e-mail) 
probably doesn't have a cache... this would only work if using the 
build-directory version of the dependency project.

The solution I proposed is probably better, as it can be used with both 
a built or installed dependency (assuming that the installed version 
references other installed versions of its own dependencies and/or the 
builds of the same are still available).

(OTOH if that last part isn't true, the transitive dependencies just 
won't be used, with either technique.)
