The point of ConfD examples is to show how to use the ConfD APIs, not how to use it with a particular build tool. Every project integrating ConfD might employ a different build tool in its own specific way, so showing a particular build tool being used in a particular way would quite likely be useless.
Yeah i know that, there is an example and there could be specific way to implement from customer point of view.
But you know that, CMakeList is an conventional and best practise. Maybe There can be just Cmake Example.
Because as i believe that many companies use CMake build system.
Usually, integrations with external implementations are added to the https://github.com/ConfD-Developer/ repository. So if you or someone else want to contribute a CMake build system demo example, a pull request with such a demo is likely welcomed.
