[cmake-developers] Proposal to teach cmDepends to only take dependencies from the source tree

[Attila Krasznahorkay]

Dear All,

I was hoping to get some feedback from the developers on which direction to take this in. As I wrote before, I'm happy to help. But I don't want to spend time on an implementation that people will not accept in the end. I'd like us to first agree on how the code should behave after the addition of this new feature.

Cheers,
              Attila
