[关于OPENCV函数未定义的]

[吱吱吱吱丶]

近期在编译一个工程，里面使用到大量OPENCV函数。

然后我去GitHub上面下载了opencv310源代码，进行cmake编译使用vs2013生成debug和release的lib库。

在qt工程的.pro文件中我是这样写的

QMAKE_CXXFLAGS += -DOPENCV_DISPLAY
INCLUDEPATH += E:\openCV\opencv\build\include
LIBS +=  -LE:\Calibrator_Unified\lib
contains(CONFIG,Debug){
message(Debug)
LIBS +=  -lopencv_core310d -lopencv_imgproc310d -lopencv_highgui310d
LIBS += -lopencv_video310d -lopencv_imgcodecs310d -lopencv_features2d310d -lopencv_calib3d310d
}
contains(CONFIG,Release){
message(Release)
LIBS +=  -lopencv_core310 -lopencv_imgproc310 -lopencv_highgui310
LIBS += -lopencv_video310 -lopencv_imgcodecs310 -lopencv_features2d310 -lopencv_calib3d310
}
LIBS += -luser32
SOURCES += DetectionDev/cornersExtraction.cpp \
    DetectionDev/datadetector.cpp \
    DetectionDev/Board.cpp \
    CalibDev/CameraCalibratorUnified.cpp \
    CalibDev/CameraUnified.cpp \
    CalibDev/Rotation.cpp \
    Displayer/Displayer.cpp \
    CalibDev/Matrix/Matrix.cpp \
    CalibDev/Matrix/MyMath.cpp \
    CalibDev/Matrix/SVD.cpp \
    CalibDev/LM/LM.cpp \
    CalibDev/Matrix/Log.cpp

HEADERS += DetectionDev/cornersExtraction.h \
    DetectionDev/datadetector.hpp \
    DetectionDev/Board.hpp \
    DetectionDev/dataType.h \
    CalibDev/CameraCalibratorUnified.hpp \
    CalibDev/CameraUnified.hpp \
    CalibDev/ColorText.hpp \
    CalibDev/dataType.h \
    CalibDev/Rotation.h \
    Displayer/Displayer.hpp \
    CalibDev/Matrix/Matrix.h \
    CalibDev/Matrix/MyMath.h \
    CalibDev/LM/LM.h \
    CalibDev/Matrix/Log.h

TARGET = Calibrator_Unified
SOURCES += MainCalibrator.cpp

但是进行编译的时候出现了下列错误（见图片）。

请各位大神解答这是什么错误？

虽然我知道这是函数未定义找不到的意思，但是我已经链接了lib库和源文件链接。

已解决！编译opencv请使用qt-opensource-windows-x86-msvc2013_64-5.5.1版本，注意vs版本号！
