调试的时候总出现一个窗口，下面是窗口的内容：
---------------------------
Debugging Helper Missing
---------------------------
The debugger could not load the debugging helper library.
---------------------------
The debugging helper is used to nicely format the values of some Qt and Standard Library data types. It must be compiled for each used Qt version separately. In the Qt Creator Build and Run preferences page, select a Qt version, expand the Details section and click Build All.
---------------------------
Continue Anyway Open Qt Options Turn off Helper Usage Hide Details...

这个问题怎么解决， debugging helper library. 是什么东西？哪里下载？
