[Qt-interest] Error trying to link .lib file

[fungos]

I'm trying to use a library that is .lib (DevIL Image Library). My .pro is this:

TARGET  = devil-qt
TEMPLATE = lib
CONFIG += plugin
VERSION = 1.0.0
QT += core gui

INCLUDEPATH += "D:/Development/libs/DevIL-SDK-x86-1.7.8/include"
win32:LIBS += "D:/Development/libs/DevIL-SDK-x86-1.7.8/lib/DevIL.lib"
"D:/Development/libs/DevIL-SDK-x86-1.7.8/lib/ILU.lib"
"D:/Development/libs/DevIL-SDK-x86-1.7.8/lib/ILUT.lib"

HEADERS += devil-qt-plugin.hpp \
		   devil-qt-handler.hpp
SOURCES += devil-qt-plugin.cpp \
		   devil-qt-handler.cpp

DESTDIR += $$[QT_INSTALL_PLUGINS]/imageformats

And when I try to build it wont find references to DevIL functions:

What is wrong there?
