Comment (by michaelld):

 OK that's what I thought. Took me a bit to track that down & install it
 for testing.

 So there are a few issues here:

 (1) mysql57 is opportunistically finding and using protobuf3-cpp . I think
 this feature can be disabled via the cmake commandline, and really it
 should be a variant  / optional.

 (2) protobuf3-cpp API (header) require C++11 for building, but mysql57
 when building the plugin that uses protobuf3-cpp isn't using C++11 ...
 it's not specifying any C++ standard, which with most compilers means
 C++03 or earlier ... certainly not C++11 yet. Without C++11, this plugin
 won't build. You can see the errors in the build log associated with this
 issue:

 And then see also < https://en.cppreference.com/w/cpp/atomic/atomic >
 where it should be noted that `std::atomic` requires C++11.
