Thanks, in fact I found the problem!
It is due to the repeated call of CollapseFullPath ("") which is used to
determine the current absolute path cmDependsC.cxx
for each dependency file with absolute path.
This call is extremely costly on the mac. And it seems completely unnecessary
because the current directory is never changed
in cmDependsC.cxx. Initialization of the otherwise unused member Directory
with the current directory and elemination of CollapseFullPath
reduced dependency determination on the mac from 2 minutes too 8 seconds.
This is even faster than for cmake 2.2.3.
I have send a patch for closer inspection of the solution
via the bug tracker.
Thanks. I've fixed it. See this for details:
