Libyui is a widget abstraction library providing Qt, GTK and ncurses frontends. It was developed for YaST.
Libyui uses CMake, driven by a slightly complex set of CMakefiles.
For reproducible builds it is best to use rubygem-packaging_rake_tasks.rpm like the Jenkins CI jobs do.
You need the base libyui library
checked out in ../libyui (or point the environment variable LIBYUI_BASE
to it).
Then run:
rake -f ../libyui/Rakefile osc:build
