Here's what I've done:

1. Downloaded qwt-4.2.0-setup-qt230nc.exe from sourceforge
2. Unpack to C:\Program Files\Qwt
3. Go to Qt Command Prompt
4. Run msvc-qmake.bat.
5. Get the [output](http://www.nopaste.pl/g3e).

Now the lib directory is created, but it's empty. Also tried opening VS project file, but it doesn't converse to VS2008, because there are no vcproj files. I also tried to do it qmake way:
`qmake qwt.pro` and then `make`, but it says make is not recognized. I figured that I could use mingw32-make, but I gave me a lot of compiler errors.

I was hoping I would use Qwt within QtCreator, but sadly failed. Any help appreciated.
