Unfortunately it does not generate +`protobuf::*` targets until CMake-3.9, and `protobuf::protoc` does not +appear until CMake-3.10. + +The CMake-config files generated by `protobuf` always create these targets, +but on some Linux distributions (e.g. Fedora>=29, and openSUSE-Tumbleweed) there +are system packages for protobuf, but these packages are installed without the +CMake-config files. One must either use the ``FindProtobuf`` module, find the +libraries via `pkg-config`, or find the libraries manually. + +When the CMake-config files are installed they produce the same targets as +recent versions of ``FindProtobuf``. However, they do not produce the +`Protobuf_LIBRARY`, `Protobuf_INCLUDE_DIR`, etc. that are generated by the +module.
