On a fresh Neon Developer Edition kaccounts-integration is not present. This for example breaks part of Purpose's functionality since it's not possible to add accounts for the Nextcloud and Youtube upload
Some proposed changes to fix this: https://invent.kde.org/neon/neon/seeds/-/merge_requests/1 https://invent.kde.org/neon/kde/purpose/-/merge_requests/1
I do wonder... shouldn't either purpose or kaccounts-providers find_package on kaccounts-integration as RUNTIME dep? Currently I don't see it codified in cmake, if it was the build tooling would have told us to add a dep somewhere.
I guess from a kaccounts devs view the issue is the kaccounts-integration source package which makes the libkaccounts library and kded_accounts gets split by Debian packaging cos that how packaging likes things and the packaging should just make sure that that daemon gets installed when the library is installed.
Should be fixed by https://invent.kde.org/neon/kde/kaccounts-integration/commit/779c08061fbff76d980e6080f7ed7d16032278c5
