Question

我从官方网站下载SDK，并使用以下命令创建新项目：

cocos new foo -p com.foo.bar -l cpp -d .

因此，新项目foo已创建，我进入其目录。我知道proj.win32有预装了visual studio的解决方案文件。但我希望从根项目目录的CMakeLists.txt重新生成它们。

所以我mkdir -p cmake-out/vs2012，输入目录，然后cmake -G "Visual Studio 11 2012" ../../。一切都很好，解决方案文件是由cmake构建的，所以我在visual studio中重建了整个解决方案。编译全部通过*，但最终链接过程因以下错误而失败：

原始解决方案没有错误，我知道。但是Visual Studio解决方案文件应该能够由cmake生成，CMakeLists.txt会出现什么问题？

*：实际上，包含目录设置是不正确的，所以我修补它们：

include_directories(
    ${CMAKE_CURRENT_SOURCE_DIR}/Classes
    ${COCOS2D_ROOT}
    ${COCOS2D_ROOT}/cocos
    ${COCOS2D_ROOT}/cocos/audio/include
    ${COCOS2D_ROOT}/cocos/2d
    ${COCOS2D_ROOT}/cocos/2d/renderer
    ${COCOS2D_ROOT}/cocos/2d/platform
    ${COCOS2D_ROOT}/cocos/2d/platform/desktop
    ${COCOS2D_ROOT}/cocos/2d/platform/win32
    ${COCOS2D_ROOT}/cocos/base

和他们一起：

include_directories(
    ${CMAKE_CURRENT_SOURCE_DIR}/Classes
    ${COCOS2D_ROOT}
    ${COCOS2D_ROOT}/cocos
    ${COCOS2D_ROOT}/cocos/audio/include
    ${COCOS2D_ROOT}/cocos/2d
    ${COCOS2D_ROOT}/cocos/renderer
    ${COCOS2D_ROOT}/cocos/platform
    ${COCOS2D_ROOT}/cocos/platform/desktop
    ${COCOS2D_ROOT}/cocos/platform/win32
    ${COCOS2D_ROOT}/cocos/base

是的，renderer，platform ...不在cocos/2d路径中。这是我必须对消息来源做的唯一改变。

如果有人再次遇到这个问题。

这是因为cocos2d cmakelists.txt无法与windows platofrm上的ws2_32库链接。显然没有人使用cocos2d-x进行Windows开发或其他什么？无论如何。

要解决此问题，请在target_link_libraries中找到CMakeLists.txt部分，然后进行更改。

寻找：

target_link_libraries(${APP_NAME}
  spine
  cocostudio
  cocosbuilder
  extensions
  audio
  cocos2d
  )

并将其替换为：

if(WIN32 AND MSVC)
  target_link_libraries(${APP_NAME}
    spine
    cocostudio
    cocosbuilder
    extensions
    audio
    cocos2d
    box2d
    ws2_32
  )
else()
  target_link_libraries(${APP_NAME}
    spine
    cocostudio
    cocosbuilder
    extensions
    audio
    cocos2d
    box2d
  )
endif()

希望能解决这个特殊问题，并且整个过程会编译而不会遇到另一个问题。
