Argh, from /usr/include/cdio/iso9660.h ..

libosinfo is licensed  LGPLv2+, so we cannot link to libiso9660.so
I'm afraid.

If there's no other possible LGPLv2+ compatible library that does
this kind of thing, then the other option is to spawn /usr/bin/iso-info
and parse the output.

Or create a /usr/libexec/libosinfo-isohelper helper binary that does
link against libiso9660.so and returns the information in a format that
is more easily consumable by libosinfo than that from iso-info binary.
