Test CMake build

Hello all.
Please test build Postgres using cmake. If you are of course interested.
Still not everything is ready but most of the work. Assembly instructions
as does the repository is on github:
https://github.com/stalkerg/postgres_cmake

The compilation will be enough (tests even better). I need feedbacks so
that create issues on github.
Very interesting NetBSD, OpenBSD, Solaris.

Thanks!
