测试代码：

<pre class="cpp" name="code">#include <opencv2/core/core.hpp>#include <opencv2/highgui/highgui.hpp>int main() {    // read an image    cv::Mat image= cv::imread("img.jpg");    // create image window named "My Image"    cv::namedWindow("My Image");    // show the image on window    cv::imshow("My Image", image);    // wait key for 5000 ms    cv::waitKey(5000);        return 0;}

出现错误：

error: undefined reference to `cv::imread(std::string const&, int)'
