+ "CMake 2.8.11 consumed the 'link interface' of a target from properties " s/consumed/constructed/ + if(te->Target->GetPolicyStatusCMP0022() != cmPolicies::NEW) This should be "not OLD and not WARN" because in the future it may be REQUIRE_ALWAYS or REQUIRE_IF_USED which are new behavior. The export() command will also need the EXPORT_LINK_INTERFACE_LIBRARIES option. In the tll() signature policy I think LINK_PUBLIC/LINK_PRIVATE should be an alias for PUBLIC/PRIVATE. The "old" signatures are only the one without any keywords plus the one with LINK_INTERFACE_LIBRARIES. The "new" signatures are the (LINK_)?(PUBLIC|PRIVATE|INTERFACE) mode. That is why we need a policy to make the old and new sigs exclusive. > An issue with static libraries arises when exporting, as we only export the > INTERFACE_LINK_LIBRARIES, but we want to communicate both link dependencies > and usage dependencies through it.
