添加系统环境变量

Path：
D:\install\OpenCV\opencv\build
D:\install\OpenCV\opencv\build\x64\vc14\bin

也有说添加如下Path:
D:\install\OpenCV\opencv\build\x64\vc14\bin
D:\install\OpenCV\opencv\build\x64\vc15\bin

新建一个win32控制台项目工程

test_opencv.cpp

#include <iostream>
#include <opencv.hpp>

using namespace std;
using namespace cv;
int main()
{
	VideoCapture cap(0);
	Mat frame;
	while (true) {
		cap >> frame;
		imshow("frame", frame);
		waitKey(10);
	}
	return 0;
}

配置项目属性

VC++目录–包含目录：
D:\install\OpenCV\opencv\build\include

VC++目录–库目录：
D:\install\OpenCV\opencv\build\x64\vc14\lib

链接–输入–附加依赖项：
D:\install\OpenCV\opencv\build\x64\vc14\lib\opencv_world341.lib;
D:\install\OpenCV\opencv\build\x64\vc14\lib\opencv_world341d.lib;

运行Release X64
