Hi @zifiri99. Thanks for taking the time to submit a pull request.

As you can see from the workflow run logs:

https://github.com/arduino-libraries/NTPClient/actions/runs/9530782946/job/26271033621?pr=210#step:3:7

Run cmake -B /home/runner/work/NTPClient/NTPClient/build -DCMAKE_BUILD_TYPE=Release
CMake Error: The source directory "/home/runner/work/NTPClient/NTPClient" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.

this project is not configured for building with CMake. We also don't have any interest in adding such a capability since we only provide official support for using the library with the official development tools provided by Arduino (Arduino IDE, Arduino CLI, Arduino Cloud Editor).

So I'll close this pull request as declined.
