Support for qBittorrent on CentOS 7 has been lacking to date so I have built an RPM.
It installs the runtime environment for both qbittorrent (GUI) and qbittorrent-nox (headless version) in /usr/local.
After installing you should find a qBittorrent icon in your GUI menu or just run 'qbittorrent'.
It is avalable here:

Please let me know if it works for you or not by posting to this topic.
