Opencv sample in Qt crashes immediately with the error 'The program has unexpectedly finished'

edit

I tried to create a simple Opencv application in Qt and upon running, the whole application is crashed. If I comment out the opencv related codes from the project, the project runs just fine.
What I did :

Downloaded the Qt 5.5.0 VS2013 64bit version   
Downloaded the OpenCV 3.0   
Downloaded the Cmake 3.3.2

There were already prebuilt binaries in when I extracted the Opencv package, But all tutorials on the net wanted me to recompile the source codes so did I.
the package contains :

build
sources

created a new folder named mymade to hold the binaries next to the other two directories.
so it now looks like this :

 build
 mymade
 sources

Steps: Fired up CMake, specified the source folder from the extracted files and specified mymade as the output for binaries.
checked all options that had a opencv in their names, plus Qt! and configured it and subsequently generated the files.
This is the resulting contents :

So all is done and I now need to build the binaries. I opened OpenCV.sln and compiled the release and debug binaries .
the dlls are placed inside bin directory, and the lib files are placed inside lib folder .
Now its the time to configure the Qt projects .pro file So I used the header files from build directory, and for libs I used the lib folder from mymade folder. This is the first configuration that I came up with, which compiles without any linker issues, but crashes just immediately.
the initial changes in project file :

#-------------------------------------------------
#
# Project created by QtCreator 2015-10-06T14:04:20
#
#-------------------------------------------------

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = OpenCVTest
TEMPLATE = app

SOURCES += main.cpp\
        mainwindow.cpp

HEADERS  += mainwindow.h


INCLUDEPATH += L://Apps_Installation_Folder//opencv//build//include
LIBS += L://Apps_Installation_Folder//opencv//mymade//lib//Release//*.lib

FORMS    += mainwindow.ui

doing this in project file as it was suggested by answers like this didnt do any good either :

#-------------------------------------------------
#
# Project created by QtCreator 2015-10-06T14:04:20
#
#-------------------------------------------------

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = OpenCVTest
TEMPLATE = app

SOURCES += main.cpp\
        mainwindow.cpp

HEADERS  += mainwindow.h


INCLUDEPATH += L://Apps_Installation_Folder//opencv//build//include

LIBS += L://Apps_Installation_Folder//opencv//mymade//lib//Release//opencv_core300.lib
LIBS += L://Apps_Installation_Folder//opencv//mymade//lib//Release//opencv_highgui300.lib
LIBS += L://Apps_Installation_Folder//opencv//mymade//lib//Release//opencv_imgcodecs300.lib
LIBS += L://Apps_Installation_Folder//opencv//mymade//lib//Release//opencv_ml300.lib
LIBS += L://Apps_Installation_Folder//opencv//mymade//lib//Release//opencv_objdetect300.lib

LIBS += L://Apps_Installation_Folder//opencv//mymade//lib//Release//opencv_flann300.lib
LIBS += L://Apps_Installation_Folder//opencv//mymade//lib//Release//opencv_features2d300.lib

FORMS    += mainwindow.ui

this fails as well :

#-------------------------------------------------

#

QT       += core gui
