Package: libprotobuf-dev Version: 3.21.12-1 CMake has difficulties to keep up compatibility with the CMake files provided by Protobuf, therefore it is considered to deprecate FindProtobuf in CMake [1] in favor of CMake files provided by Protobuf.
One way to add the CMake files could be to switch from Autotools to CMake or Bazel. These tools are recommended to build Protobuf from source [2]. The instructions to build Protobuf with Autotools have been removed [3].
