Missing definitions from 0.9.0 #205
Description
When trying to compile against master I am getting the following linker errors:
Undefined symbols for architecture arm64:
"cel::base_internal::MessageTypeFieldCount(unsigned long)", referenced from:
cel::base_internal::LegacyStructType::field_count() const in libdata.a(struct_type.o)
"cel::interop_internal::ProtoStructValueToMessageWrapper(cel::Value const&)", referenced from:
cel::interop_internal::ToLegacyValue(google::protobuf::Arena*, cel::Handle<cel::Value> const&, bool) in libinterop.a(interop.o)
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I don't see a definition for the first one:
https://github.com/search?q=repo%3Agoogle%2Fcel-cpp%20MessageTypeFieldCount&type=code
Though the second one seems to be defined here: https://github.com/google/cel-cpp/blob/58397d797f2c98e2450e5b1df3d5b2048f1e7499/extensions/protobuf/struct_value.cc#L74
though without the ABSL_ATTRIBUTE_WEAK

The first one seems to be just missing, the second one seems to be a cycle in the dep graph, that is being 'solved' via ABSL_ATTRIBUTE_WEAK:
I suspect the problem with the second one is, the xcode linker used on macos does not respect the weak attribute.
