CMake 2.8

[hoijui]

CMake 2.8 got released on 2009_11_04
more here:
http://www.kitware.com/news/home/browse ... +Available
most interesting changes for us, seem to be faster makefile dependency scanner and improved find modules.
these dont need adjustment of our scripts.. the only other hting, which would need adjustment, is the option to have a list of predefined values for a propertiy (so you can select them from a list in the cmake GUI). i dont think that this is worth moving to 2.8.

mammadori reported an error with a find script of ours, and that happend in 2.8, cause variables in if statements can not be used anymore in the same way it was possible before (i think they removed the <varname>-NOTFOUND convention).
there is a policy we can set though, to activate that again, until we changed everything.

I'll paste the above mentioned debug message below since it may disappear in few days from that URL.

I am using 2.8 some time already, and didn't had any problems with it. Neither did I got the error from mammadori (which btw seems more like an cmake / installation error rather than a spring one).

i dont think that this is worth moving to 2.8.

Well, I already moved to 2.8.

I think hoijui means by moving dropping compatibility for versions before 2.8. (Correct me if I'm wrong.)

If that is the case, that seems indeed somewhat extreme requirement just to get lists of options in the ccmake UI.

exactly what tobi said
