undefined reference in Qt creator for DCMTK libraries - c++

Question

I'm trying to run a simple application in Qt creator using DCMTK libraries and it doesn't work as it should. I receive the following message:
error: undefined reference to `DicomImage::DicomImage(char const*, unsigned long, unsigned long, unsigned long)'
main.cpp:
#include "dcmtk/config/osconfig.h"
#include "dcmtk/dcmdata/dctk.h"
#include "dcmtk/dcmimgle/dcmimage.h"
#include "iostream"
int main(int argc, char *argv[])
{
DicomImage *image = new DicomImage("test.dcm");
if (image != NULL){
std::cout << "hell yeah!";
}
return 0;
}
.pro file:
#-------------------------------------------------
#
# Project created by QtCreator 2016-02-18T19:16:51

QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

win32:LIBS += -lAdvapi32 -lofstd -loflog -ldcmdata -ldcmnet -ldcmimage -ldcmimgle -lws2_32 -lnetapi32 -lwsock32
I think something is wrong with .pro file but I cannot figure out. I have included the necessary libraries and still no use.. I read that for DCMTK the order of libraries is important but I think it is already in order and cannot figure out what could be. Can you provide a solution to this problem?
