对于一个学校项目，我想在CLion上安装OpenCV。
我下载了适用于windows的OpenCV安装程序，并在C:disk上提取了OpenCV。我在系统环境变量中添加了OpenCV lib和bin文件夹的路径。
这是我的CMakeList.txt文件：
cmake_minimum_required(VERSION 3.23)
project(poumons VERSION 0.1.0)
include(CTest)
enable_testing()
find_package(OpenCV REQUIRED)
include_directories( ${OpenCV_INCLUDE_DIRS} )
add_executable(poumons main.cpp)
target_link_libraries( poumons ${OpenCV_LIBS})
set(CPACK_PROJECT_NAME ${PROJECT_NAME})
set(CPACK_PROJECT_VERSION ${PROJECT_VERSION})
include(CPack)
以下是CMake构建的输出：
"C:Program FilesJetBrainsCLion 2022.2.4bincmakewinbincmake.exe" -DCMAKE_BUILD_TYPE=Debug "-DCMAKE_MAKE_PROGRAM=C:/Program Files/JetBrains/CLion 2022.2.4/bin/ninja/win/ninja.exe" -G Ninja -S C:UsersaxellCLionProjectspoumons -B C:UsersaxellCLionProjectspoumonscmake-build-debug

这是源文件：
#include <iostream>
#include <opencv2/opencv.hpp>
using namespace cv;
int main() {
std::cout << "Hello, World!" << std::endl;
/*Mat image;
image = imread("./moi.png");
imshow("fenetre" ,image);
waitKey(0);*/
cv::Mat image2;
return 0;
}
但当我构建项目时，这里是输出：

我试着使用Visual Studio代码来查看我的OpenCV是否安装正确，它运行得很好，但在CLion上没有。
我不知道我错过了什么或做错了什么。
谢谢。
我也面临同样的问题。对于解决方案，我只需编辑clion构建设置就足够了。你在visual studio代码中使用的是哪个构建，你应该像这样编辑你的clion设置。在这里输入图像描述
