QT Help support build directories

When I try to build this project in QT I get this error.
"QMake does not support build directories below the source directory"

I tried different things but had no luck so far.
To open this project I double clicked on MakeQD.pro
C:\QD3.0.0Source\QD3\questdesigner3\MakeQD.pro

I tried to fix this error by going to "tools/options". Then went to Projects.
Under the general tab, I tried to change the project directory to fix this error(assume this is where I need to go to fix) but no luck.

I'm using windows. Using QT version 2.0.1
Says it's based on Qt 7.0

Need more details?

if you enter the error message into google you will find this site with an explanation on the top.
