I need to check this in detail, but my intuition is that the new protobuf 4.23 added a depedency on abseil in the public headers, so it is necessary that all downstream users of protobuf link abseil. However, CMake's FindProtobuf (the one used by default if one calls find_package(Protobuf) ) has not been updated to handle that, so abseil is not linked.

Possible solutions:

• Fix CMake's FindProtobuf
• Switch to use find_package(Protobuf CONFIG) so that the protobuf-config.cmake file installed by protobuf is used
• Link manually abseil

with the additional abseil dependency we now need to make sure that all compilation units are compiled with the same version of C++ used to compile abseil. Unfortunatly, CMake is not equipped to do this check automatically (see https://gitlab.kitware.com/cmake/cmake/-/issues/22592 and abseil/abseil-cpp#259).

Actually the Protobuf gz-cmake machinery actually looks first for the protobuf with CONFIG, see https://github.com/gazebosim/gz-cmake/blob/d618dd70c0862d8e6c9ee9aa6d776bc30bf2f19c/cmake/FindGzProtobuf.cmake#L29 . However, that is failing (and hence falling back to the FindProtobuf cmake script) with error:

The reason is https://github.com/gazebosim/gz-msgs/blob/460d563c6437731e3c89df2342228a1889390902/CMakeLists.txt#L85 . Basically we pass 3 as required protobuf version. The related commits are from 5/6 years ago:

• gazebosim/gz-msgs@718587e
• gazebosim/gz-msgs@0bfcad3

As the only Ubuntu distribution with protobuf 2 is Ubuntu 16.04 (in EOL since a long time ago), I guess we can just drop the requirement.

Cross-compilation is now failing on osx-arm64:

From what I understand, the trick of passing the Protobuf_PROTOC_EXECUTABLE variable does not work anymore, either because it never worked with find_package(Protobuf CONFIG) or because something changed in recent releases in the protobuf-config.cmake file, I am not sure.

because something changed in recent releases in the protobuf-config.cmake file

I think the latter is the case, see:
