运行错误：“...error while loading shared libraries: libopencv_core.so.3.4...”

[HuixiangLiu]

环境：Ubuntu 14.04 + OpenCV 3.4.1 + QT 问题：EasyPR安装，命令模式下运行Demo都没问题，在QT环境中 测试代码如下： int main(void) { // QCoreApplication a(argc, argv); // return a.exec(); CPlateRecognize pr; pr.setResultShow(false); pr.setDetectType(PR_DETECT_CMSER);

    vector<CPlate> plateVec;
    Mat src = imread("/home/liu/EasyPR-master/result.jpg");
    int result = pr.plateRecognize(src, plateVec);

}

Debug 时 没有错误，但出现很多警告，弹出窗口显示： /home/liu/code/build-EasyPR-Desktop-Debug/EasyPR: error while loading shared libraries: libopencv_core.so.3.4: cannot open shared object file: No such file or directory Press to close this window...

请问各位大神，不知这个错误跟哪个文件有关，如何修改？ 我的.Pro 如下：
