c++ - 实例化 Mat 对象时 opencv 3.0.0 链接器错误

Question

我正在尝试编译一个简单的 opencv 程序。我已经设置了环境变量，还设置了项目的 C++ 附加包含目录以及 额外的链接器目录和输入依赖项(opencv_ts300d.lib 和 opencv_world300d.lib)但我一直收到此代码的链接器错误:

    #include<iostream>
#include<opencv2\opencv.hpp>
#include<cstdio>
#include <string>
#include <opencv2\core\core.hpp>
#include <opencv2\imgcodecs.hpp>
#include <opencv2\highgui\highgui.hpp>

using namespace std;
using namespace cv;

int main(int argc, char** argv)
{
    cv::Mat a;
    return 0;
}

错误如下:

当我遇到这种情况时，我正在链接到 OpenCV 库的 x64 版本，但试图编译成 x86 (Win32) 应用程序。只是从 32 bit to 64 bit application 改变让我的工作成功。
