【ROS2 Foxy】解决 connext 中间件导致的警告：NDDSHOME environment variable has not been set

问题背景

执行安装命令：

sudo apt install ros-foxy-rmw-connext-cpp

终端出现警告：

[connext_cmake_module] Warning: The location at which Connext was found when the workspace was built [[/opt/rti.com/rti_connext_dds-5.3.1]] does not point to a valid directory, and the NDDSHOME environment variable has not been set. Support for Conne

解决方法

这里我不想用这个中间件了，所以选择直接卸载：

sudo apt purge ros-foxy-rmw-connext-cpp
sudo apt purge ros-foxy-connext-cmake-module
