libxcb-icccm4-dev binary package in Ubuntu Lunar i386

 This package contains the header and library files needed to build software
 using libxcb-icccm, providing client and window-manager helpers for ICCCM.
 .
 The xcb-util module provides a number of libraries which sit on top of
 libxcb, the core X protocol library, and some of the extension
 libraries. These experimental libraries provide convenience functions
 and interfaces which make the raw X protocol more usable. Some of the
 libraries also provide client-side code which is not strictly part of
 the X protocol but which have traditionally been provided by Xlib.
