required CMake version

[tdev]

it seems that the cmake version requirement should be increased.

tested to compile with (default debian lenny cmake)

Code: Select all

# cmake -version
cmake version 2.6-patch 0

which throws the following error:

Code: Select all

/var/lib/hudson/jobs/Ogre3d/workspace/CMakeLists.txt:23:
Parse error.  Function missing ending ")".  Instead found left paren with text "(".
-- Configuring done

after installing cmake-2.8 the error went away. So i propose to increase

Code: Select all

cmake_minimum_required(VERSION 2.6.2)

I think we could up it even more, although we might upset some Debian stable user.. Not sure.
Why not at least 2.8 ?
CABAListic knows for sure.

I'd rather underestimate the required version than overestimate it, so as not to accidentally exclude any version that would actually work fine. But given that 2.6.0 does not work, an increase to 2.6.2 would probably be fine. If anyone is willing to find the exact minimum required version, I'd appreciate it.
