libqxt installation problem - features.path warning

I use Qt SDK 1.1.1 (everything installed exept experimental category) on Windows 7 and I'm trying to set up libqxt libaries for this enviroment. I downloaded and unpacked libqxt tip and ran configure.bat file using Qt for Desktop command line with -static -debug_and_release properties as administrator.

Testing for qmake...
Testing for mingw32-make...Using mingw32-make.

If tests fail, some features will not be available.

Configuration successful.
Generating makefiles...

ed backslashes are deprecated.
WARNING: features.path is not defined: install target not created
Makefiles generated. Run mingw32-make now.

And so mingw32-make command do nothing... What should I do to compile it properly. I tried to use diffrent parameters but nothing changes...

Run

mingw32-make -f Makefile

After it completes then run

mingw32-make -f Makefile install

This should install the Qxt library in C:\Qxt.

I have reached this far but the QXT widgets are not showing up in QT creator.
