ROS2进阶：在windows10上用vs2019编译rviz2

首先给出重点，

打开vs2019的命令窗口，

>call C:\dev\ros2_humble\local_setup.bat
> mkdir -p d:/vROS2/rviz2_ws/src
> cd d:/vROS2/rviz2_ws/src
> git clone --recursive https://github.com/ros2/rviz.git  rviz2

>cd  rviz2

>git checkout humble

>cd ..

>cd ..
> colcon build --merge-install

 期间碰到两个问题。

第一个问题：找不到patch.exe。

Starting >>> rviz_ogre_vendor
--- stderr: rviz_ogre_vendor
