这个错误提示说明CMake在配置OpenCV时，未能找到epoxy库。epoxy是一个OpenGL库，它提供了对OpenGL的直接访问。在安装OpenCV时，如果启用了OpenGL支持，那么epoxy库是必须的。
解决方法
你需要安装libepoxy库及其开发头文件。下面是解决这个问题的步骤：
-
安装
libepoxy库打开终端并运行以下命令来安装
libepoxy库：sudo apt update sudo apt install libepoxy-dev

一键安装ros后，opencv也自动安装了。
下面是手动安装的教程。

由此链接进入boost官网：https://www.boost.org/
tar -xzvf boost_1_77_0.tar.gz
cd boost_1_84_0/
sudo ./bootstrap.sh
sudo ./b2 install安装libssl-dev
sudo apt-get install libssl-dev安装orbslam3
git clone https://github.com/UZ-SLAMLab/ORB_SLAM3.git
这个看运气 ，运气好就能git到。翻墙增加成功率。
cd ORB_SLAM3
chmod +x build.sh
./build.sh
修改/home/cyk/ORB_SLAM3/CMakeLists.txt
重新安装Pangolin
tracking.cc报错
sed -i ‘s/++11/++14/g’ CMakeLists.txt
报错：internal compiler error
修改./build.sh
最后一行make -j4改为make
gedit ~/.bashrc/home/cyk/ORB_SLAM3/Examples_old/ROSexport ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:/home/cyk/ORB_SLAM3/Examples_old/ROSsource ~/.bashrc

export ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:/home/cyk/ORB_SLAM3/Examples/ROS
Examples中是没有ROS这个文件夹的，需要自己去Examples_old中手动复制过去。
chmod +x build_ros.sh

#include <sophus/se3.hpp>
解决1：找到ORB_SLAM3/Examples_old/ROS/ORB_SLAM3下的CMakeLists.txt 修改它，include_directories中添加

接下来的报错：
原文链接：https://blog.csdn.net/weixin_48924581/article/details/126534339
解决：
(1)找到ORB_SLAM3/Examples_old/ROS/ORB_SLAM3/src/AR下的ros_mono_ar.cc文件：
将第151行的 cv::Mat Tcw = mpSLAM→TrackMonocular(cv_ptr→image,cv_ptr→header.stamp.toSec());
替换为：
cv::Mat Tcw;Sophus::SE3f Tcw_SE3f = mpSLAM->TrackMonocular(cv_ptr->image,cv_ptr->header.stamp.toSec());Eigen::Matrix4f Tcw_Matrix = Tcw_SE3f.matrix();cv::eigen2cv(Tcw_Matrix, Tcw);(2)找到ORB_SLAM3/Examples_old/ROS/ORB_SLAM3/src/AR下的ViewerAR.cc文件：
将第405行的vPoints.push_back(pMP→GetWorldPos());
替换为：
cv::Mat WorldPos;
cv::eigen2cv(pMP->GetWorldPos(), WorldPos);
vPoints.push_back(WorldPos);(3)还是ViewerAR.cc文件：
将532行的cv::Mat Xw = pMP→GetWorldPos();
替换为：
cv::Mat Xw;
cv::eigen2cv(pMP->GetWorldPos(), Xw);重新编译
报错3：
解决：加头文件
在/ORB_SLAM3/Examples_old/ROS/ORB_SLAM3/src/AR/ViewerAR.h中加入如下：
#include <Eigen/Dense>
#include <opencv2/core/eigen.hpp>
#include <opencv2/opencv.hpp>再次重新编译，可算ok了
