Package fails to build with Clang 16, due to -Wenum-constexpr-conversion (this seems to affect quite some packages...).

Just seen this with kde=apps/kdepim-runtime-23.04.02
Could one of you report this upstream please & link it here? Thanks.
https://invent.kde.org/pim/kdepim-runtime/-/commit/be465b7480555e7ae6a26c1c8acb71aafa991927 Please test 23.08.5.
I can confirm that kde-apps/kdepim-runtime-23.08.5 builds with clang, while earlier versions failed.
