Extend the interface of the target_compile_features command with PUBLIC and INTERFACE keywords. Populate the INTERFACE_COMPILER_FEATURES target property if they are set. Consume the INTERFACE_COMPILER_FEATURES target property from linked dependent targets to determine the final required compiler features and the compile flag, if needed. Use the same pattern of origin-debugging which is used for other build properties.
