integrating Qt with visual c++ 2008

Hello, help me!
I have done the integration with QT and visual c++ 2008, I have done the configuration like “http://rajorshi.net/blog/2009/01/using-qt-with-msvc-express-2008/comment-page-2/#comment-35272”, now Qt is integrated with Visual c++ 2008, soh, when I run the project “HelloQt” that I created…..

1>—— Build started: Project: HelloQt, Configuration: Debug Win32 ——
1>Performing Makefile project actions
1>’qmake’ não é reconhecido como um comando interno
1>ou externo, um programa operável ou um arquivo em lotes.
1>Project : error PRJ0019: A tool returned an error code from “Performing Makefile project actions”
1>Build log was saved at “file://c:\Users\lulu\Documents\Visual Studio 2008\Projects\HelloQt\HelloQt\Debug\BuildLog.htm”
1>HelloQt – 1 error(s), 0 warning(s)
====== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ======
