This way journalctl can make use of libqrencode if it's there, but will quietly not use it if it isn't. This means libqrencode remains a build-time dep, but not a strict runtime dependency. I figure we should do something similar for a bunch of other "leaf" libraries we only use few symbols of. Specifically the following are probably good candidates: * pcre2 * libpwquality * p11kit * elfutils and possibly: * libcryptsetup (only in some parts. i.e. building systemd-cryptsetup without it makes no sense. However building the dissect option with libcryptsetup as optional dep does make sense) * possibly the compression libraries (at least the ones we never use for compression, but only as alternative ones for decompression) Already covered like this is: * libxkcommon
