## Using c library We can also set ``proto_public = true`` to export the proto's header search directory and make it available for other parent targets to inherit from. ```lua add_packages("protobuf-c", {public = true}) add_files("src/**.proto", {proto_public = true}) ``` ::: tip NOTE Since the headers generated by protobuf reference the headers of the protobuf-c package, we also need to mark the package headers as `{public = true}` to export it. ::: ## Using the C++ library We can also set ``proto_public = true`` to export the proto's header search directory and make it available for other parent targets to inherit from. ```lua add_packages("protobuf-cpp", {public = true}) add_files("src/**.proto", {proto_public = true}) ``` ::: tip NOTE Since the headers generated by protobuf reference the headers of the protobuf-cpp package, we also need to mark the package headers as `{public = true}` to export it. :::
