Optimize: Cache initial cmake variables
Review Request #110580 - Created May 21, 2013 and submitted
Do not call `cmake --system-information` for every project - cache it instead. On my system this call takes ~1s and thus in my favorite session this slows down startup by ~5-10s (1s for every project I have open in that project). I post the review request here because I'm not sure whether there are use cases where we do not want this behavior. Like a system upgrade where system information variables changed. But then again - we don't actually reload the project there anyways... So - is this OK? Aleix? Also - should this maybe also use the cmake binary configured for a given project? That would be for a different patch then of course. Just interested.
Ran the stuff. Seems to work :]
