From: Dan McGregor <[email protected]> Use this recipe to break a circular dependency between libfido2 and systemd when systemd's fido PACKAGECONFIG is enabled. systemd depends on libfido2, and libfido2 depends on udev provided by systemd. However, systemd only depends on the headers provided by libfido2 and its pkgconf data. systemd uses only the datatypes provided, and opportunistically enables fido support if libfido2 is found.
This recipe provides only the headers and pkgconf data. This is sufficient to allow systemd to build support for libfido2. It only works with a related change I've submitted to openembedded core.
