loading matlab using Qt error

I have successfully loaded matlab files using visual studio 13.0

Now I want to do same with Qt but getting errors. here is my .pro file

Code:

QT       += core gui
 
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
 
TARGET = matlabtest
TEMPLATE = app
 
INCLUDEPATH += "C:\Program Files\MATLAB\R2014a\extern\include"
 
SOURCES += main.cpp\
        mainwindow.cpp \
    stdafx.cpp
 
HEADERS  += mainwindow.h \
    stdafx.h\
    targetver.h
 
FORMS    += mainwindow.ui
 
 
INCLUDEPATH += $$PWD/
DEPENDPATH += $$PWD/
 
win32: LIBS += -L$$PWD/ -llibeng
win32: LIBS += -L$$PWD/ -llibmat
win32: LIBS += -L$$PWD/ -llibmex
win32: LIBS += -L$$PWD/ -llibmx

I have copied the library files into my own project directory... when I run the program using following code

Code:

#include "mainwindow.h"
#include <QApplication>
#include "stdafx.h"
#include "engine.h"
#include "cmath"
#include "stdlib.h"
using namespace std;
 
#pragma comment (lib, "libmx.lib")
#pragma comment (lib, "libmex.lib")
#pragma comment (lib, "libmat.lib")
#pragma comment (lib, "libeng.lib")
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();
 
    engine *promat;
    promat = engOpen("null");
    engEvalString(promat, "eval('final1022');");
    return a.exec();
}

I get error as below

Quote:

main.obj:-1: error: LNK2019: unresolved external symbol _engEvalString referenced in function _main

main.obj:-1: error: LNK2019: unresolved external symbol _engOpen referenced in function _main

how can I fix this... note that this works fine with VS2013
