In short, adding to %cmake: -DINCLUDE_INSTALL_DIR=%{_includedir} \\ -DLIB_INSTALL_DIR=%{_libdir} \\ -DSYSCONF_INSTALL_DIR=%{_sysconfdir} \\ -DSHARE_INSTALL_PREFIX=%{_datadir}

Found these additions useful while working on kde4 packaging (SYSCONF_INSTALL_DIR in particular, since kde4's default was/is prefix/etc).
