If you run `apt install virt-manager` it will install virt-manager,
libvirt, qemu and everything needed to run and use the software.
If you run `apt build-dep libvirt` it will install everything needed to
compile libvirt but not necessarily everything you need to actually run
it. If you do only build-dep for libvirt you will have no virt-manager
and you would not be able to use it. You would have only libvirt.
