Example doesn't compile (MacOS)

[JC3]

The example program here:

#include <string>
#include <zmq.hpp>
int main()
{
   zmq::context_t ctx;
   zmq::socket_t sock(ctx, zmq::socket_type::push);
   sock.bind("inproc://test");
   const std::string_view m = "Hello, world";
   sock.send(zmq::buffer(m), zmq::send_flags::dontwait);
}

Doesn't seem to compile, due to multiple errors:

You should specify c++ version (to be equal to or higher than 11). If using g++ add -std=c++11. If using cmake set(CMAKE_CXX_STANDARD 11).
