Is there a C ++ CalDav protocol library for connecting to iCloud // Yahoo

Is there a C ++ library that implements this protocol?
There are always many good open-source libraries that implement standardized protocols such as CalDav.
They are best hunted by FOSS project hosts (using Google).
Here are a few: -
