Hi to all!

I am trying to compile qt 4.7.0 app that integrades LUA scripting language in Qt Creator 2.0.1 under Windows 7 Ultimate. At compile time, I get following errors:
debug/mainwindow.o:C:\Users\HP2\Desktop\ABTeamTestApp-build-desktop/../ABTeamTestAppWC/mainwindow.cpp:32: undefined reference to `luaL_newstate' debug/mainwindow.o:C:\Users\HP2\Desktop\ABTeamTestApp-build-desktop/../ABTeamTestAppWC/mainwindow.cpp:35: undefined reference to `luaL_openlibs'
collect2: ld returned 1 exit status
mingw32-make[1]: *** [debug\ABTeamTestApp.exe] Error 1
mingw32-make: *** [debug] Error 2
The process "C:/Qt/2010.05/mingw/bin/mingw32-make.exe" exited with code %2.
Error while building project ABTeamTestApp (target: Desktop)
When executing build step 'Make'
When executing build step 'Make'.
Now, the reason for error is following method:
Qt Code: 
  1. void MainWindow::initLUA()
  2.  
  3. {
  4.  
  5.     lua_State* L=lua_open();
  6.  
  7.     if(!L)
  8.  
  9.         qFatal("LUA cannot be initialized.");
  10.  
  11.     luaL_openlibs(L);
  12.  
  13. }

I am checking my .pro file (for including dlls and libs)
and I am getting nowhere. Here is .pro file:
