我正在尝试从http://docs.opencv.org/doc/tutorials/introduction/display_image/display_image.html#display-image编译和运行 DisplayImage OpenCV 示例，但是
cmake输出：
-- Configuring done

-- Build files have been written to: /home/####/Desktop/OpenCV/image
make输出：
Linking CXX executable DisplayImage
[100%] Built target DisplayImage
和./DisplayImage image.jpg输出：
