can't compile kde4 apps

[Orgad Shaneh]

last version of the kdelibs5-dev package (4.1.2-0ubuntu11) breaks compilation of kde4 apps using cmake.

using previous version (4.1.2-0ubuntu10) works fine on the exact same environment.

example of kipi-plugins from svn (using cmakekde script from here: http://techbase.kde.org/Getting_Started/Increased_Productivity_in_KDE4_with_Scripts/.bashrc):
