CLion 和 CMake 没有抱怨，但无法构建 OpenCV

问：

总结

在 Windows 中，CLion 在 cmake 之后和 makefile 之前不会抱怨任何内容。

• 所有代码似乎都正确链接，没有错误。我能够看到参考文献、文档、linter 并使用 .cv::Matopencv.hppctrlRMB
• CMake 似乎正确生成了 make 文件，没有错误。

但是编译错误发生：OpenCV 方法。undefined reference to

我的设置

CMakeLists.txt:

cmake_minimum_required(VERSION 3.9)

project(test)

# Set compile version
set(CMAKE_CXX_STANDARD 17)
add_executable(test ./test.cpp )
find_package(OpenCV REQUIRED)

message(STATUS "OpenCV library status:")
message(STATUS "    version: ${OpenCV_VERSION}")
message(STATUS "    libraries: ${OpenCV_LIBS}")
message(STATUS "    libraries: ${OpenCV_LIBRARIES}")
message(STATUS "    include path: ${OpenCV_INCLUDE_DIRS}")

target_link_libraries(test ${OpenCV_LIBRARIES})

输出似乎是正确的

这会产生 ，其中包括，CMakeCache.txt

//The directory containing a CMake configuration file for OpenCV.
OpenCV_DIR:PATH= /path/to/scoop/apps/opencv/current/x64/vc15/lib

//Details about finding OpenCV
FIND_PACKAGE_MESSAGE_DETAILS_OpenCV:INTERNAL=[/path/to/scoop/apps/opencv/current][v4.5.5()]

如您所见，CLion 已经设置并正确读取了系统范围的环境变量。OpenCV_DIR

这是一个简单的测试代码，但运行失败

#include <opencv2/opencv.hpp>
int main() {
    cv::Mat img = cv::imread("./test.jpg", -1);
    cv::imshow("Mon image", img);
    cv::waitKey(0);
    return 0;
}

我还安装了 from 和 from installed ， ， ，。按照本教程进行操作。 通过该工具链而不是 CLion 捆绑工具链进行测试，它返回相同的结果。msys2wingetmsys2clangmakeMinGW-w64 GDBcmake

OpenCVbinary 来自 。scoop

出于某种原因，它与自制软件存在相同的问题。在 中，由于 opencv.hpp 位于 opencv2 文件夹中的文件层次结构，包含标头不正确。 我把所有都改成了，但它没有帮助，反之亦然。opencv.hpp#include "opencv2/header.hpp"#include "header.hpp"

几个小时都搞不清原因..任何帮助将不胜感激。
