Once I've built Qwt, how do I add it to a form in Designer?

Hi guys,
I still can't solve this problem. qwt compiled ok. Installed ok. I even added a copy of qwt_designer_plugin5.dll to the qt/bin folder.

What else could be causing the error:

"Cannot load library C:/Qt/2009.01/qt/plugins/designer/qwt_designer_plugin5.dll: The specified module could not be found."

You need to make sure that you have the main Qwt bin directory in your path (or lib directory depending upon where the DLLs are). I created my own bin directory and copied the Qwt DLLs from the lib directory over because that's where I expect to see DLLs.

Anyways, since you already copied the Qwt plugin DLL to the designer plugins directory, the problem is likely NOT that it can't find the Qwt plugin ... but rather that it can't find the main Qwt DLL.
