The CMP0022 NEW behavior is that the INTERFACE_LINK_LIBRARIES property exactly defines the link interface. The plain target_link_libraries signature says linking is transitive by default, so it should populate the property. Teach the target_link_libraries plain signature to populate the INTERFACE_LINK_LIBRARIES regardless of the CMP0022 setting. Refactor the cmTarget::ComputeLinkInterface checks that warn when the policy is not set to compare the new property to either the explicitly set old link interface properties or the link implementation fallback for all linkable target types, not just static libraries. This fixes a regression in 2.8.12.0 that caused target_link_libraries to not implement transitive linking in the plain signature once the policy CMP0022 is set to NEW.
