opencv有错误为什么还是可以运行通过
#include "StdAfx.h"
#include "highgui.h"

int main()
{
const char* imagename = "D:/Demo.jpg"; //随便放一张jpg图片在D盘或另行设置目录
cv::Mat img = cv::imread(imagename);

if(img.empty())return -1; //是否加载成功
if(!img.data)return -1;

cv::namedWindow("image", CV_WINDOW_AUTOSIZE);
cv::imshow("image", img);
cv::waitKey();
return 0;
}

[解决办法]
它运行的是你上次成功生成的exe文件。
