[CMake] FYI - From Ninja-build mailing list - Fwd: Proposal: restat rules

Hi Bill,

Here are some timing, I made for ITK to compare ninja vs make (made  
last month). See results below

The difference is not much, especially when you realized that none of  
the data have been downloaded, and I am not sure that at the end we  
get the same binary tree...

Encouraging matter of fact, it worked on ITK...

my 2 cts,
Arnaud
