The policy warning is only issued if 

1) Both LINK_INTERFACE_LIBRARIES and INTERFACE_LINK_LIBRARIES are set on a 
single target (either by using set_property or by using the various 
target_link_libraries signatures).

2) You export() or install(EXPORT) a target which has 
LINK_INTERFACE_LIBRARIES set, but which does not use the new 
EXPORT_LINK_INTERFACE_LIBRARIES option to those commands to cause it to be 
exported to the targets file, even though the policy is set to NEW.


There may be a bug there, or a chance to emit a warning we're not currently 
emitting. Please file a bug with a testcase if that is the case.

Thanks,

Steve.
