使用CMake生成MFC項(xiàng)目的時(shí)候，需要用到在共享DLL中使用 MFC，需要在CMakeLists文件中加上如下的代碼：
ADD_DEFINITIONS(-D_AFXDLL)
SET(CMAKE_MFC_FLAG 2)
ADD_EXECUTABLE(detect WIN32 ${DIR_SRCS})
CMAKE_MFC_FLAG參數(shù)的意思是這樣解釋的：
To use MFC, the CMAKE_MFC_FLAG variable must be set as follows:
0: Use Standard Windows Libraries
1: Use MFC in a Static Library
2: Use MFC in a Shared DLL
