1. I don't know but nobody objections if we install latest CMake under
Windows or MacOSX but many if under Linux/*BSD. I have builded CMake
recently under old Solaris without any problems.

2. I use "graceful degradation" method and currently target is 3.0 version
BUT time to time I testing and backporting the code. I hope I can make all
features for 2.8.4 .

3. Please do not compare cmake and GNU Make. CMake it's like Autotools with
detect library scripts out the box. Every new version brings not only new
functions and syntax construction. Most fix in find_library scripts.
Besides you can't build project without gnu make, make, nmake, ninja and
etc because CMake generate files for another make systems. On this basis,
to CMake can not meet the same requirements for version as GNU Make. It is
quite another thing.

PS Special for Postgres in CMake 3.6 I implemented features for replace
gen_def.pl script under MSVC.
