And another. Here is new documentation I've written based on this
discussion. Please update the topic to implement the tll() behavior
with respect to the policy and LINK_PUBLIC.
this->DefinePolicy(
CMP0019, "CMP0019",
"Use INTERFACE_LINK_LIBRARIES instead of LINK_INTERFACE_LIBRARIES.",
"A CMake shared library target (or an executable with the "
"ENABLE_EXPORTS property) may be given a \"link interface\" "
"determining the libraries that must be linked by its dependents. "
"CMake 2.8.10 and lower used the LINK_INTERFACE_LIBRARIES and "
"LINK_INTERFACE_LIBRARIES_<CONFIG> target properties "
"to determine the link interface. "
"CMake 2.8.11 and higher prefer the single "
"INTERFACE_LINK_LIBRARIES target property "
"to determine the link interface. "
"The new property supports generator expressions "
"to specify configuration-specific link libraries."
"\n"
"This policy is not considered when loading IMPORTED targets. "
"However, it does affect how the export() and install(EXPORT) "
"commands generate imported targets for use in dependent projects. "
"\n"
"The OLD behavior for this policy is to ignore the new "
"INTERFACE_LINK_LIBRARIES property and use the old "
"LINK_INTERFACE_LIBRARIES(_<CONFIG>) properties to determine the "
"link interface. "
"Targets named after LINK_PUBLIC in target_link_libraries will "
"populate the old properties and not the new. "
"The export() and install(EXPORT) commands will generate only the "
"IMPORTED_LINK_INTERFACE_LIBRARIES(_<CONFIG>) properties on a "
"target to be imported into other projects, and not "
"INTERFACE_LINK_LIBRARIES. "
"\n"
"The NEW behavior for this policy is to ignore the old "
"LINK_INTERFACE_LIBRARIES(_<CONFIG>) properties and use the new "
"INTERFACE_LINK_LIBRARIES property to determine the link interface. "
"Targets named after LINK_PUBLIC in target_link_libraries will "

"The export() and install(EXPORT) commands will generate the new "
"INTERFACE_LINK_LIBRARIES property on a target to be imported "
"into other projects. "
"They will generate IMPORTED_LINK_INTERFACE_LIBRARIES(_<CONFIG>) "
"properties only if LINK_INTERFACE_LIBRARIES(_<CONFIG>) have been "
"set explicitly on the target to be exported."
"\n"
"The setting for this policy used to determine the link interface is "
"that in effect when the target is created by an add_library or "
"add_executable command.",
2,8,11,0, cmPolicies::WARN);
Thanks,
