I would like to export my protobuf-files into a separate directory. After reading through the FindProtobuf.cmake I found out, that there is an option PROTOC_OUT of generate_protobuf_cpp that does exactly that, but seems to be undocumented. As this option exists since at least v3.16 (that I use), I’m wondering why it is not documented? If it simply has been forgotten, I would try and change the documentation myself (and probably add functionality to create this folder if it doesn’t exist).
Thanks and best regards
