I'd mention explicitly that cagibi is a run-time dependency in 
macro_log_feature.
Something like
macro_log_feature( CAGIBI_FOUND
"Cagibi" "SSDP (Simple Service Discovery Protocol, used by UPnP) cache/proxy 
daemon" "http://websvn.kde.org/trunk/kdesupport/cagibi/" FALSE
  ${CAGIBI_MIN_VERSION} "Runtime dependency that provides UPnP 
device/service listing in the network:/ kioslave."

BTW, what about adding one more parameter to m_l_f that tells whether 
dependency is a runtime dep (default to FALSE)? Or even add another macro 
because "required" flag MUST be FALSE for runtime dependencies? Then we'll 
be able to say:
