title: gRPC-only Tensorflow Serving client in C++
body: <p>There seems to be a bit of information out there for creating a <code>gRPC</code>-only client in Python (and even a few other languages) and I was able to successfully get a working client that uses only <code>gRPC</code> in Python that works for our implementation.</p>
  
  <p>What I can't seem to find is a case where someone has successfully written the client in C++.</p>
  
  <p>The constraints of the task are as follows:</p>
  
  <ol>
  <li>The build system cannot be <code>bazel</code>, because the final application already has its own build system.</li>
  <li>The client cannot include <code>Tensorflow</code> (which requires <code>bazel</code> to build against in C++).</li>
  <li>The application should use gRPC and not HTTP calls for speed.</li>
  <li>The application ideally won't call Python or otherwise execute shell commands.</li>
  </ol>
  
  <p>Given the above constraints, and assuming that I extracted and generated the <code>gRPC</code> stubs, is this even possible?  If so, can an example be provided?</p>
