If this helps anyone, I'm working on a large project using CMake and in two different computers, both with the same version of Ubuntu and cmake, it is *REALLY SLOW* in only one of them while scanning dependencies, but it's not in the other laptop. (The "slow" dep. scanning is ~1 min. too)
I'd be happy to help debugging this, because it's really annoying :-( Regards, Jose Luis On Thu, Dec 4, 2008 at 12:46 AM, Senanu Pearson <[EMAIL PROTECTED]>wrote: > > Hi folks, > > >> Is there a way to speed up the dependency scan in version 2.6? >> >> I recently installed a new Linux OS (Mandriva 2009) which included an >> upgrade to cmake 2.6 (I _think_ I had version 2.4 before).
