Build passes here
(In reply to Agostino Sarubbo from comment #3) > Build passes here That's cause it depends on <dev-libs/protobuf-23:=[${MULTILIB_USEDEP}] now. The problem is still there, it just pulls in an older version now.
Like with other packages this is fixed by using the cmake config files instead of FindProtobuf.cmake. Doing so is trivial, biggest hurdle would be seeing if upstream is fine with it due to other distributions leaving them out. So for an upstreamable solution it could be case of trying first config and then non config. Or trying config and then pkgconfig.
