frameworks branch now requires CMake 2.8.6 RC 2

[Stephen Kelly]

Hi,

As I noted before, I have now made the frameworks branch require cmake 
2.8.6-RC2.

* http://www.kitware.com/blog/home/post/160
* git clone kde:extra-cmake-modules

As before, this is a rolling dependency at the moment, so I will be updating 
it as newer release candidates of cmake become available.

The 2.8.6-RC2 version of cmake includes working automoc support.

It is very cool, and I suggest you all try it out on your non-kde-frameworks 
projects too. (Just set(CMAKE_AUTOMOC ON) in your project).

GenerateExportHeader is also in this version of cmake, so I have removed the 
copy from kde cmake/modules.

With these features it is possible to build individual kde frameworks 
standalone. I can now cmakekde in itemmodels or in tier1 (because the tier1 
libraries do not have dependencies on each other).

Please review the ECMQtFramework.cmake file which makes this possible.

Thanks,

Steve.
