[cmake-developers] Introduce 'Unix Ninja' generator

[Daniel Levin]

As far as I understand this 'env' is not a standard key in Ninja, right?
That would be actually great to let CMake define environment variables in
rules.
Does CMake support that already?
What about Makefile compatibility, is it possible to define env variables
per rule in Makefiles?
