[CMake] Progress reporting in CMake

[Denis Scherbakov]

Dear CMake Gurus,

Can you, please explain, how progress reporting in CMake is organised? I have a project with more than 100 files organised into subprojects. Still progress jumps from 0% to 4% ... from 14% to 19%. Why is that?

Frankly speaking, I've never seen in any of my CMake projects (including small ones) correct progress reporting.
