# The purpose of this recipe is to break a circular dependency between libfido2 and
# systemd. libfido2 depends on udev (provided by systemd) to build, while systemd
# depends on libfido2 if the fido feature is enabled. However, systemd doesn't
# actually link against libfido2. It only needs the headers in place and a dummy
# shared library. It opportunistically dlopens libfido2 if it's present, but
# for that to work it needs the headers in place.
# Just fake enough to make systemd happy, and have it RRECOMMEND the real libfido2.
