I faced a similar warning with libkdcraw, which uses the KDE4_ADD_LIBRARY 
macro ( which calls set_target_properties(${_target_NAME} PROPERTIES 
LINK_INTERFACE_LIBRARIES "" ) )

I was told that LINK_INTERFACE_LIBRARIES is the old property and 
INTERFACE_LINK_LIBRARIES is the new one. 

It was suggested on #kde-devel that it would be better to just suppress the 
warning.

Hope that helps.
