CMake构建Visual Studio中MFC项目的MFC配置问题
使用CMake生成MFC项目的时候，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码：
ADD_DEFINITIONS(-D_AFXDLL)
SET(CMAKE_MFC_FLAG 2)
ADD_EXECUTABLE(detect WIN32 ${DIR_SRCS})
CMAKE_MFC_FLAG参数的意思是这样解释的：
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

But it is the same with man as with the tree. The more he seeks to rise into the height and light, the more vigorously do his roots struggle earthward, downward, into the dark, the deep - into evil.
其实人跟树是一样的，越是向往高处的阳光，它的根就越要伸向黑暗的地底。----尼采
