How to compile Opencv 3.1 with QT on a x64 machine?

Question

I'm using Opencv 3.1, Cmake 3.6.0, Cuda 7.5, Visual Studio 2013.
I successfully compile my own Opencv libraries, on a x64 machine and I am able now to use CUDA module.
I tried to compile it with qt 5.6.1 but I couldn't.
When I select the checkbox WITH > QT on cmake-gui I have no problems. But when I build the ALL BUILD project it throws me the followings:

window_QT.obj : error LNK2001: unresolved external symbol "public: static struct QMetaObject const ...

I've already use the qt instaler and compile qt from source.
I've already put the lib and bin directories on the VSproject, but I cannot resolve the linking problem.
Thanks..

For OpenCV 3.1, here is the configuration that worked for me:

TEMPLATE = app
CONFIG += console c++11
CONFIG -= app_bundle
CONFIG -= qt

SOURCES += main.cpp
TARGET = main

INCLUDEPATH += C:/opencv-3.1.0/opencv/build/include
LIBS += -LC:/opencv-3.1.0/opencv/build/x64/vc14/lib
LIBS += -LC:/opencv-3.1.0/opencv/build/x64/vc14/bin

CONFIG(debug,debug|release)
{
    LIBS += -lopencv_world310d
}

CONFIG(release,debug|release)
{
    LIBS += -lopencv_world310
}

To add Qt support to OpenCV 3.1, please follow these instructions: https://gist.github.com/BartG95/1ce8ba1e9c25ec3698d1

and add /APPCONTAINER:NO to the following properties during the build process, otherwise it will not work:

CMAKE_EXE_LINKER_FLAGS
CMAKE_MODULE_LINKER_FLAGS
CMAKE_SHARED_LINKER_FLAGS

Here is my working .pro file:

TEMPLATE = app
CONFIG += console c++11
