Can't run Qt program connected with OpenCV

[Beibut]

When I run program on QT creator, simple program which uses OpenCV.
Have an error: cannot open file 'opencv243d.lib' (file not found)

Here is my pro file.
INCLUDEPATH += C:\Opencv243\opencv\build\include
INCLUDEPATH += C:\opencv243\opencv\build\include\opencv2

LIBS += -LC:\Opencv243\opencv_bin\lib
-lopencv_core243d
-lopencv_highgui243d
-lopencv_imgproc243d
-lopencv_features2d243d
-lopencv_calib3d243d
-lopencv_video243d
-lopencv_objdetect243d
-lopencv_ml243d
-lopencv_legacy243d
-lopencv_imgproc243d
-lopencv_flann243d
-lopencv_gpu243d

Please help me.

First of all don't use in path a \ - replace it with /
Then clear project, run qmake and try build/rebuild.
If that doesn't help then make sure that opencv* are in PATH variable.

Can you paste here a pro file and some errors? It's looks that linker can't find lib or symbols in lib.

My OpenCV version is 2.4.6, to include the PATHs and LIBS I did the code as follows, to this version of OpenCV you don't have to use the Cmake to compile the files, just add according to your system. Try to adapt the code to suit your situation.

@QT += core

QT -= gui

TARGET = ShowImage
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app

SOURCES += main.cpp

INCLUDEPATH += C:\opencv\build\include
INCLUDEPATH += C:\opencv\include

LIBS += -LC:\opencv\build\x86\vc11\lib
-lopencv_calib3d246d
-lopencv_contrib246d
-lopencv_core246d
-lopencv_features2d246d
