I linked the exact commit I meant in 'next'.  I'll look at this one now.

It's used to generate -Wl,-rpath-link (or platform equivalent) options
when linking consumers of a library target.  It needs to be populated with
whatever dependencies are linked by the original shared library but are not
in its link interface.  That distinction is per-config and is now harder to
compute.

BTW, have you thought through how CMP0019 will deal with static libraries?
Their IMPORTED_LINK_INTERFACE_LIBRARIES is always the "link implementation"
as specified by tll(), but it is not maintained directly in the original
LINK_INTERFACE_LIBRARIES property.

Feel free to rewrite the staged topics as much as you want to keep things
tested as they evolve from this discussion.

Thanks,
