Binary package “libdbus-glib-1-dev” in ubuntu focal

deprecated library for D-Bus IPC (development files)

 D-Bus is a message bus, used for sending messages between applications.
 Conceptually, it fits somewhere in between raw sockets and CORBA in
 terms of complexity.
 .
 This package provides development files for a deprecated GLib-based
 D-Bus library. New code should use GDBus, part of GLib, instead.
 .
 See the dbus description for more information about D-Bus in general.
