I've changed that now in the branch. Effort is made to not populate the 
property, and even if it does get populated, the value is not exported.

The patch I added does not need to be reverted. So we're just left in an 
intermediate state temporarily where exported static libraries do not get 
their INTERFACE_LINK_LIBRARIES populated, even when they should. That can be 
fixed when the followup topic is merged.

Thanks,

Steve.
