Please update to CMake 2.4.5 or newer
do you still have CMake 2.4.3 installed on your KDE4 development system ? Then it's time to upgrade to CMake 2.4.5 or newer. Because starting Monday in a week, March 19th, at least CMake 2.4.5 or newer will be required for building KDE4.
So what will CMake 2.4.5 bring us compared to 2.4.3 ?
So, please update your CMake to version 2.4.5 or 2.4.6 until next Monday, March 19th if you haven't done so yet.
