I'll help wherever support from the buildsystem is needed.

Yes, having a KDE4RUNTIME_DBUS_INTERFACES_DIR would be the correct solution.

For now, how about the following:
PATHS ${DBUS_INTERFACES_INSTALL_DIR} 
      ${KDE4_DBUS_INTERFACES_DIR}
      ENV XDG_DATA_DIRS

At least from the buildsystem view, installing every module into its own 
prefix is (should be) supported. At least whenever I encounter a problem with 
this I consider this a bug.
