Question

我想在Windows上为CLion IDE设置OpenCV。我尝试使用OpenCV 3.1和2.4，结果相同。我有Windows 10 64位。克里昂正在使用cygwin environement。

到目前为止我做了什么：
1。从OpenCV下载exe并运行它（它提取了一个包）。我的路径是E：/ opencv
2。添加了OpenCV_DIR变量并将其添加到路径中
3。将此添加到我的项目CMakeLists.txt：

set(OpenCV_LIB_PATH E:/opencv/build/x64/vc12/lib)
set(OpenCV_LIB_DIR E:/opencv/build/x64/vc12/lib)
set(OpenCV_LIBS E:/opencv/build/x64/vc12/lib)
set(CMAKE_PREFIX_PATH E:/opencv/build)
set(OpenCV_DIR E:/opencv/build/x64/vc12)
include_directories(E:/opencv/build/include)
FIND_PACKAGE(OpenCV REQUIRED)

target_link_libraries(good ${OpenCV_LIBS} )

我设法在我的程序中使用OpenCV Mat（库是可见的）但是在尝试打开图像时收到错误。
我的节目是:(只是一个例子）

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <iostream>


using namespace cv;
using namespace std;

int main( int argc, char** argv )
{
    string imageName("../data/test.png");
    if( argc > 1)
    {
        imageName = argv[1];
    }
    Mat image;
    image = imread(imageName.c_str(), IMREAD_COLOR);
    if( image.empty() )
    {
        cout <<  "Could not open or find the image" << std::endl ;
        return -1;
    }
    namedWindow( "Display window", WINDOW_AUTOSIZE );
    imshow( "Display window", image );
    waitKey(0);
    return 0;
}

问题是：当我运行项目时，我收到错误：

非常感谢。
