libgladeui-dev 3.40.0-1 (arm64 binary) in ubuntu lunar

 Glade is a RAD tool to enable quick and easy development of user
 interfaces for the GTK+ toolkit.
 .
 Glade is, since its "3.0" major version, highly modular, and composed
 of widgets which can be used by other applications to integrate
 functionality similar to the one provided by the Glade application
 itself.
 .
 This library provides all the widgets and core code, like parsing and
 saving files.
 .
 This package contains the development files and documentation for the
 library.
