所以我正在尝试构建一个简单的opencv代码，但我一直收到此错误，我似乎没有在互联网上找到任何解决方案：
os：Windows 8.1
编译器GNU GCC 601
IDE：CLION
CMake 3.0和mingw64
这是我从opencv教程page
获得的代码#include <stdio.h>
#include <opencv2/opencv.hpp>
using namespace cv;
int main(int argc, char** argv )
{
if ( argc != 2 )
{
printf("usage: DisplayImage.out <Image_Path>\n");
return -1;
}
Mat image;
image = imread( argv[1], 1 );
if ( !image.data )
{
printf("No image data \n");
return -1;
}
namedWindow("Display Image", WINDOW_AUTOSIZE );
imshow("Display Image", image);
waitKey(0);
return 0;
}
和CMake文件：
cmake_minimum_required(VERSION 3.0)
project(opencv)
set("OpenCV_DIR" "C:/opencv/build")
find_package( OpenCV REQUIRED )
include_directories( ${OpenCV_INCLUDE_DIRS} )
add_executable(opencv exemple.cpp)
target_link_libraries( opencv ${OpenCV_LIBS} )
我得到了这个错误。我检查了文件夹C：/ opencv / build / lib /并且它是空的
