我的 PC 上安装了 QT，它使用 Visual Studio 2010 编译器
我用一个简单的 hello world 应用程序对此进行了测试，它运行良好。
但是现在我正在尝试将 OpenCV 与 QT 一起使用。我已经安装了 Visual Studio 2010 express 和 professional，并且 opencv 在那里工作正常。但是，当我尝试在 QT 中运行 OpenCV 时，出现以下错误
main.obj:-1: error: LNK2019: unresolved external symbol "public: void __thiscall cv::Mat::deallocate(void)" (?deallocate@Mat@cv@@QAEXXZ) referenced in function "public: void __thiscall cv::Mat::release(void)" (?release@Mat@cv@@QAEXXZ)

我尝试链接到以下 FirstProject.pro 内容，但一点也不好

以下是我的代码
主文件
#include <iostream>
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
using namespace std;
using namespace cv;
int main()
{
Mat image = imread("D:/Tulips.jpg");
if(!image.data)
{
cout << "Error loading image" << endl;
}
else
{
namedWindow("Image");
imshow("Image",image);
}
waitKey(0);
return 0;
}
为什么我会收到此错误？
