Qt小技巧5.解决"Failed to extract plugin meta data"问题

1. 使用Qt插件开发时，在debug模式下加载插件时遇到如下问题：
   

"Failed to extract plugin meta data from './ICE-PCPUd. dll'""ICE-PCPUd. dll"
Found invalid metadata in Lib ./ICE-PBAKMINId. dll: Unexpected metadata contents

2. 分析原因是安装Visual Studio时未安装update升级包，我用的vs2015+Qt5.12.6，下载链接：

3. 重新安装vs2015（带update）问题就解决了；
4. 附带vs其它版本下载链接：
