Question

我使用的是Opencv 3.1，Cmake 3.6.0，Cuda 7.5，Visual Studio 2013。
我在x64机器上成功编译了自己的Opencv库，现在我可以使用CUDA模块了我尝试用 qt 5.6.1 编译它，但我不能当我选中复选框 WITH＆gt;关于cmake-gui的QT 我没有问题。但是当我构建ALL BUILD项目时，它会抛出以下内容：

window_QT.obj：错误LNK2001：未解析的外部符号＆＃34; public： static struct QMetaObject const ...

我已经使用qt instaler并从源代码编译qt 我已经把lib和bin目录放在了VSproject上，但我无法解决链接问题谢谢..

Answer 1

对于OpenCV 3.1，以下是适用于我的配置：

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
}

Answer 2

要向OpenCV 3.1添加Qt支持，请按照以下说明操作：https://gist.github.com/BartG95/1ce8ba1e9c25ec3698d1

并在构建过程中将/APPCONTAINER:NO添加到以下属性，否则将无效：

CMAKE_EXE_LINKER_FLAGS
CMAKE_MODULE_LINKER_FLAGS
CMAKE_SHARED_LINKER_FLAGS

这是我工作的.pro文件：

TEMPLATE = app
CONFIG += console c++11

CONFIG -= qt

SOURCES += main.cpp
TARGET = main

如何在x64机器上使用QT编译Opencv 3.1？
