[cpprest] Example of using the cpprest client library code?

Description

I've recently started using swagger-codegen to generate the cpprest client code for my swagger spec. The code all compiles and links swell in my C++ app.

But, how do I actually use it from my C++ application? I've seem to have initialized the ApiClient and ApiConfiguration. But it's not clear to me how to incorporate the getXXX() call on my API object (ex: DefaultApi).

I've done a rather extensive internet search for source code demonstrating using the generated client code, but to no avail. I've also noted there is the swagger-codegen sample petstore client library for cpprest at tree/master/samples/client/petstore/cpprest but is there a test harness for it anywhere? Am I missing something obvious? (Be kind, I'm new to swagger/cpprest)

Swagger-codegen version

2.3.1

Start with samples/client/petstore/cpprest and inspect whether it demonstrates initializing ApiClient and ApiConfiguration before calling DefaultApi methods. Check whether a test harness exists for that sample; done would be a clear, runnable example showing how a generated cpprest client is used from a C++ application.
