internal error: no project could be found for

Dear All,

I am newbie in Qt Programming.. I starting to use QtDesigner to build mainwindow.ui. But when I right click and select Go to slot... and select signal, error message appeared :

"internal error: no project could be found for"

I have googling this problem, and I find :
http://bugreports.qt.nokia.com/browse/QTCREATORBUG-2516

But I don't understand how to build project using cmake.

How to solve this problem step by step ?

Thanks..

Environment :
Windows 7 Ultimate 32 bit
Using qt-sdk-win-opensource-2010.05

FYI,
I have solved this problem. Just build this application, and close QtDesigner, and re-open it again. And I can select go to slot... without any problem.
