Because this value is not used. It is cached into 
KDE4_AUTH_POLICY_FILES_INSTALL_DIR, and this is a CACHE value. So I should 
use -DKDE4_AUTH_POLICY_FILES_INSTALL_DIR=share/polkit-1/actions in every KDE 
module? Or I can supply some option while compiling kdelibs?

BTW, don't you think that installing neither to polkit prefix nor to the 
current CMAKE_INSTALL_PREFIX is a strange behaviour?
