The CMake content in Eric’s PR is based on an early version that I wrote many months ago.  I’m currently working on taking those components out of his request, reviewing it, I’m already addressing some minor details, cleaning up the organization a bit, double checking details relative to the broader practices across the community (e.g. Clang’s CMake config) and then I’ll finally do some initial testing (“in mono-repo” and “out of mono-repo” across a few platforms). 

Once things seem OK I will re-issue just the CMake portion as a new pull request.
