Created attachment 249295 [details] Patch to enable YubiKey support This adds an option to build kc with YubiKey support. I shortened the install message and updated it with information on YubiKey support. Everything that was there is in the Changelog where we are already pointing the users, and this way it doesn't spam the output while installing - i.e. other messages are obvious, too. I also changed OPTIONS_RADIO to OPTIONS_SINGLE for _CLI, as far as I understood _SINGLE makes sure that there's only one option that can be selected, and these are mutually exclusive. But if I'm being honest, I would have thought the same thing about _RADIO, am not really sure, I just went with what I read in the porter's handbook.
