我已经在Ubuntu上构建了Emgucv，那么下一步是什么？

export PKG_CONFIG_PATH=/usr/local/emgucv/lib/pkgconfig:$PKG_CONFIG_PATH
export PATH=$PATH:/usr/local/emgucv/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/emgucv/lib

source ~/.bashrc

source ~/.profile

#include <emgu/emgu.hpp>
#include <emgu/opencv/opencv.hpp>

using namespace Emgu;
using namespace cv;

int main(int argc, char** argv)
{
    // Load an image
    Mat image = imread("test_image.jpg");

    // Display the image
    imshow("Display Image", image);

    // Wait for a key event
    waitKey(0);

    return 0;
}

g++ `pkg-config --cflags --libs opencv4` -o test_emgucv test_emgucv.cpp
./test_emgucv
