Libyui is a widget abstraction library providing Qt, GTK and ncurses frontends. Originally it was developed for YaST but it can be used in any independent project.
This part contains the GTK graphical front end.
Libyui uses CMake, driven by a slightly complex set of CMakefiles. For reproducible builds it is best to use the libyui-rake Ruby gem like the Jenkins CI jobs do.
It can be installed from rubygems.org using this command (Ruby needs to be installed in the system):
gem install libyui-rake
Then to build the package run:
rake osc:build
