I'd think that even Stephen Kelly can't produce idiomatic CMake 3.5  while using CMake 2.8. Although who knows.

This is a lie though because it's using cmake 3 features. It won't build  with cmake 2.8 at all.

Yes, I looked at the code and it's very similar to what is being suggested  today:

Header-only libraries don't seem to enumerate dependencies though:

Yes, but I think its evolved since then. At least that is what is seems from watching Effective Cmake talk at C++Now this year.  Utlimately, some authors will want to make their cmake standalone, which will require enumerating the dependencies, but we can't have some cmake scripts that can be used standalone and others that require being invoked with a root cmake. We need the build scripts to be consistent, and we need to support both scenarios.
