Simple gRPC demo

Welcome to this simple gRPC test project. In this repository you will find a minimal example for using gRPC. To keep the footprint low, certain dependencies are expected to already be present on the system you are compiling this on.

These are:

• gRPC itself (be aware of potential consequences of installing gRPC globally; installation through a package manager or into a custom install location are recommended; see root CMakeLists.txt to configure a custom location)
• Abseil (required by gRPC)

This simple service provides a Hello World client and server, as well as the corresponding build system. The server is implemented as a callback server, which you can read more about here; it is currently (2025) the preferred way of implementing a gRPC server.
