我正在尝试让 OpenCv2.4.6 与 QT5.1.0 一起使用到目前为止，我一直遵循本指南Qt creator 5.0.1 with OpenCv 2.3.4 on windows
不幸的是，在完成示例应用程序的试用后（在 QtCreator 中使用 OpenCv 显示图像，我收到以下错误：
[Project-Path]\main.o:-1: In function `main':
[Project-Path]\main.cpp:8: error: undefined reference to `cv::imread(std::string const&, int)'
[Project-Path]\main.cpp:9: error: undefined reference to `cv::namedWindow(std::string const&, int)'
[Project-Path]\main.cpp:10: error: undefined reference to `cv::_InputArray::_InputArray(cv::Mat const&)'
[Project-Path]\main.cpp:10: error: undefined reference to `cv::imshow(std::string const&, cv::_InputArray const&)'

“[]”路径是我的格式，应该有助于跟踪。

你能帮我解决这个问题吗？我找不到任何适用于我的案例的解决方案...
