Yes, I mean SimpleAmqpClient. But let me make it very clear that I do not wanna rant about that build process.
It is just hard as a "getting started experience" compared to the Java examples, which were ready to run after a few minutes.

My thinking goes as follows:

AMQP is a wire protocoll like http. 
There are several http clients for sure. But there is not one http client for Apache web server, a different http client for nginx and a third one for Microsoft Internet Information Services (IIS).
So why there are clients for RabbitMQ and Apache qpid and so forth, and not a generic C++ client for AMQP 1.0?
