I think, git not changes timestamps of my *.cpp files on commit, only on 
checkout (if I change branch)
Make looks to .git directory and timestamp of any git file is changed.
If I previously use ninja, no any *.cpp file was changes, buf "explain" 
give me

EXPLAIN("recorded mtime of %s older than most recent input %s (%d vs %d)"...
and
EXPLAIN("command line changed for %s", output->path().c_str());

if I comment this, only changed *.cpp file was build
