Issue with WinSock when adding the AUTOMOC to cmake file

Question

I have a problem while I am writing the cmake file. I have a project which both uses the Qt and WinSock2. But when I add set(CMAKE_AUTOMOC ON) to the CMake code, it gives me these errors:

Error 4 error C2011: 'sockaddr' : 'struct' type redefinition C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\include\ws2def.h 212 Error 5 error C2059: syntax error : 'constant' C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\include\ws2def.h 390 Error 6 error C3805: 'constant': unexpected token, expected either '}' or a ',' C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\include\ws2def.h 390 ...

And my cmake file is as follows:

PROJECT(RFIDVis-core)
CMAKE_MINIMUM_REQUIRED(VERSION 2.8.0 FATAL_ERROR)
#INCLUDE(../cmake/commonconf.cmake)


set(CMAKE_AUTOMOC ON)
#set(CMAKE_INCLUDE_CURRENT_DIR ON)

Answer: The problem is that the windows.h is going to be added to the project after adding the AUTOMOC. So, the solution is to add **add_definitions(-DWIN32_LEAN_AND_MEAN)** to the cmake file. Then, the windows.h will not include the winsock and you can include it by yourself in your project — mmostajab, Aug 28 '14 at 13:02
