请问 c++用怎样正确的静态编译呢? 目的是让编译的程序不在依赖 libopencv_*.so 文件

测试代码如下:

cv-test.cc

#include <opencv2/opencv.hpp>
#include <iostream>

int main(int argc, char** argv) {
        cv::Mat image = cv::imread("image.jpg");
        if (image.empty()) {
                std::cout << "Error loading image!" << std::endl;
                return -1;
        }
        // cv::imshow("Image", image);
        std::cout << "size: "
                << image.cols << "x" << image.rows
                << std::endl;
        return 0;
}

c++ -o cv-test cv-test.cc -I/usr/local/opencv/include/opencv4/ -L/usr/local/opencv/lib64/ -lopencv_core -lopencv_imgcodecs

正常编译

加上 -static尝试静态编译 (opencv 是有编译静态库的/usr/local/opencv/lib64/libopencv_core.a)

c++ -o cv-test cv-test.cc -I/usr/local/opencv/include/opencv4/ -L/usr/local/opencv/lib64/ -lopencv_core -lopencv_imgcodecs -static

请问大佬有没有办法静态编译
