使用AppWizard来生成一个类型为Custom AppWizard类型的工程，编译出错！

生成一个空的工程，在向导中分别选择
Standard MFC AppWizard steps和DLL,结果没添加任何语句，编译出错。class CMFCActiveXFormClassWizardAppWiz : public CCustomAppWiz
{
public:
virtual CAppWizStepDlg* Next(CAppWizStepDlg* pDlg);

virtual void InitCustomAppWiz();
virtual void ExitCustomAppWiz();
virtual void CustomizeProject(IBuildProject* pProject);
};error C2061: syntax error : identifier 'IBuildProject'why??
