1、依赖功能包安装

        sudo apt install ros-noetic-robot-state-publisher

        sudo apt-get install ros-noetic-robot-localization libmetis-dev

2、boost版本

        boost版本查看：cat /usr/include/boost/version.hpp | grep "BOOST_LIB_VERSION"

        boost官方链接：Version 1.78.0

boost安装：

        版本查看：dpkg -s libgtsam-dev  | grep Version

        保证版本不低于4.03

4、修改CmakeList.txt

        set(CMAKE_CXX_FLAGS "-std=c++11")更改为set(CMAKE_CXX_STANDARD 14)

5、修改include utility.h

        #include <opencv2/opencv.hpp>替换#include <opencv/cv.h>

        并且该头文件在pcl的头文件下面
