coco2d-x 3.0 alpha1 添加 #include "CocosGUI.h" 头文件时出现链接错误

coco2d-x 3.0 alpha1 添加 #include "CocosGUI.h" 头文件时出现链接错误

开发环境： win8.1 vs2012  coco2d-x 3.0 alpha1

现在想在 新建的工程里添加：
UILayer* layer = UILayer::create();
UIButton* uiButton = UIButton::create();
等控件时，引入的头文件和命名空间是：
#include "CocosGUI.h"
using namespace gui;
出现链接错误是：
1>HelloWorldScene.obj : error LNK2019: unresolved external symbol "public: __thiscall gui::UIMargin::UIMargin(void)" (??0UIMargin@gui@@QAE@XZ) referenced in function "void __cdecl gui::`dynamic initializer for 'UIMarginZero''(void)" (??__EUIMarginZero@gui@@YAXXZ)

///////////////////////////////////////// 解决方法 /////////////////////////////////////////////////////////////////////////////////////////////////////

设置 
[c/c++ -> Generel -> Additional Include Directories ->]
$(EngineRoot)
$(EngineRoot)cocos\
$(EngineRoot)cocos\gui

Linker 设置
[Linker->General->Additional Library Directories]
$(EngineRoot)build\Debug.win32
如果是release 需要设置release相应的目录

链接中却少相应的 lib库
[Linker->Input->Additional Dependencies]
libGUI.lib
libCocosStudio.lib
libExtensions.lib

设置相应的头文件及命名空间
#include "CocosGUI.h"

USING_NS_CC;
using namespace gui;

注意：在新版中 extensions/CCControl 系列不再维护了。

而是使用重新设计新的GUI框架，在cocos/gui下面。
