[libvirt] [libvirt-jenkins-ci PATCH 02/18] ansible: Add initial support for building projects

[Andrea Bolognani]

Building projects is entirely controlled by Jenkins in a production
environment, but it can be useful to trigger builds via Ansible
during development to figure out build dependencies and for sanity
checking purposes.
