I don't see anything in Peter's example which couldn't be implemented in
cmake 2.8? It's best practice cmake 2.8-3.0 no doubt, but cmake >= 3.5,
I don't think so.

I find the lack of clear separation of concerns problematic; the lack of
cmake support for header only libraries unfortunate; far too much hard
coding of volatile config goes on inside each library; I am unsure how
this design would be easily adaptable to C++ Modules support; I don't
find this approach particularly reusable by unknown third party cmake,
though I can see why Peter will disagree with that.

But one or two minor quibbles aside, as a cmake 2.8 design, it's great,
and I'd far prefer this approach over what some others have suggested.
Indeed its single biggest strength will be its strong familiarity to
cmake users, the cmake gurus have done a great job banging the drum on
designs like this over what came before.
