链接器在 macos 上找不到特征符号

问：

我正在尝试编写一个程序，并使用了一些 Eigen 功能。当我尝试运行它时，我在下图中出现错误，说“未定义的架构符号x86_64”和“ld：找不到架构x86_64的符号”。由于 Eigen 是一个仅标头库链接器，因此在我看来不应该处理它，但我收到错误并且无法修复它。我安装了带有 brew 的 Eigen，我的 mac 有英特尔处理器。 下面是我的CMakeLists，.txt和错误输出。

cmake_minimum_required(VERSION 3.25)

project(testCDMTrack)

set(CMAKE_CXX_STANDARD 17)

find_package(PkgConfig REQUIRED)
#find_package(Eigen3 CONFIG REQUIRED)
find_package(OpenCV REQUIRED)
#find_package(jsoncpp CONFIG REQUIRED)

set(EIGEN_ROOT_DIR "/usr/local/include/eigen3/")

include_directories(
        ${EIGEN_ROOT_DIR}
)
add_executable(testCDMTrack main.cpp CircularEdgeSampler.h CircularEdgeSampler.cpp)

target_link_libraries(testCDMTrack PRIVATE ${OpenCV_LIBS})

我试图将 Eigen 作为 pkgconfig 提供，并且我还尝试通过 CMake 标志向目录显示，但是。无法让它工作。此外，我在这里检查了大多数答案是否有类似的问题，但没有一个答案对我有用。

这是 CircularEdgeSampler.sample 在 main 中的用法。

int temp = CESampler.sample(rotationMatrices[idx], translation, _edges, samples);

这是头文件。

#ifndef TESTCDMTRACK_CIRCULAREDGESAMPLER_H
#define TESTCDMTRACK_CIRCULAREDGESAMPLER_H

#include <vector>
#include "type.h"
#include <Eigen/Core>

class CircularEdgeSampler {
public:
    int sample(Matrix33f& rotation, Eigen::Vector3f& translation, std::vector<Circle3f> _edges, std::vector<EdgeSample>& samples);
};


#endif //TESTCDMTRACK_CIRCULAREDGESAMPLER_H

这就是 In the Source 的定义。

#include "CircularEdgeSampler.h"

using namespace Eigen;

int CircularEdgeSampler::sample(Matrix33f& rotation, Eigen::Vector3f& translation, std::vector<Circle3f> _edges, std::vector<EdgeSample>& samples)
{
}

我削减了定义，以免占用太多空间。

这是错误。
