kdelibs stopped setting several CMake policies to old values, as well as
setting an old minium required CMake version.
This causes the configuration stage to fail here, as libkvkontakte sets a
higher minimum required CMake version that sets the CMP0022 policy to NEW and
causes things to fail:
CMake Error in libkvkontakte/CMakeLists.txt:
Target "kvkontakte" has policy CMP0022 enabled, but also has old-style
LINK_INTERFACE_LIBRARIES properties populated, but it was exported without
the EXPORT_LINK_INTERFACE_LIBRARIES to export the old-style properties
