先說解決方法：
因為我出現這個比較奇特，我再下面環境中的第一個項目有這個問題，但是不知道怎么瞎折騰就搞定了，不報這個異常了
不論是Qt Creator直接運行Debug或者Release都沒問題
但是我后續建立的項目始終有這個問題，經過幾天的折騰發現新項目如果使用sudo命令啟動程序就不會報異常，所以目前我的Qt Creator也用sudo命令啟動。
下面的方法我都沒有嘗試過，但是應該最貼近根本原因的。
至於為什么同一個Qt Creator創建並打開的第一個項目正常，但是后續的就異常，目前還不清楚，后續調查清楚了再來更新。
先介紹一下環境：
Ubuntu 16.04
Qt 5.10
Caffe封裝的人臉檢測庫
錯誤原因：
Caffe中用到的libprotobuf版本與Qt中引用的版本沖突
具體異常如下：
Debugging starts
