That's great news.
What is the branch name/link to these improvement?
Is it possible to push these improvements partially?

Maybe CMake community could continue working on that improvement?
It will be great to create ticket, in which propose solution will be
described.

BTW: Do you know why the Xcode and MS Visual Studio is slower than CMake
one ?

Here is the benchmarks for my internal project:

Xcode generation:
   real 6m31.733s
   user 4m51.862s
   sys 0m20.268s

Make generation:
   real 4m45.089s
   user 2m56.117s
   sys 0m17.481s

Ninja generation:
  real 2m48.585s
  user 2m30.712s
  sys 0m6.313s
