1.從http://qt-project.org/downloads 下載最新的爲vs2010編譯的qt library和VS add-in
2.依次安裝qt library 和VS add-in
3.打開VS2010,依次打開qt5->qt options->Qt versions,單擊add,在彈出的對話框裏點擊Path後面的路徑選擇按鈕，我這裏是(C:\Qt\Qt5.0.1\5.0.1\msvc2010),他會自己檢測該目錄bin下面是否有qmake.exe,如有OK按鈕可以按下，沒有則重新選擇。
4.打開VS2010,新建項目就看見qt5的模板了。
我在根據qt5模板建立項目的時候彈出錯誤
