QT报错：Building MFC application with MD[d] (CRT dll version) requires MFC shared dll version 错误已解决

QT报错：Building MFC application with /MD[d] (CRT dll version) requires MFC shared dll version 错误已解决 我用qt开发SDK时，遇到了sdk的demo调用mfc头文件stdafx.h的情况，本来想着直接把stdafx.h头文件放到相应目录下就ok了，结果编译的时候报错Building MFC application with /MD[d] (CRT dll version) requires MFC shared dll version，然后根据提示直接在stdafx.h头文件中加入了#define _AFXDLL宏定义解决了报错。
