ROS2 Error: Could not find a package configuration file provided by “turtlebot3_msgs“
官网上安装方法是这样的，不知道是否是python版本原因，最新版本没有安装成功，
Installing ROS 2 on Windows — ROS 2 Documentation: Galactic documentation
所以我试了一下微软的办法，Windows上安装ROS2，如下，
ROS 2 Binary Installation - ROS on Windows
安装完后按下面的办法测试运行，
Navigation 2 on Windows using Turtlebot 3 - ROS on Windows
指令如下，
mkdir D:\ros2prj\nav2_ws\src
pushd D:\ros2prj\nav2_ws
curl -o nav2.repos https://raw.githubusercontent.com/ms-iot/ROSOnWindows/master/docs/ros2/navigation2_foxy.repos
vcs import src < nav2.repos
colcon build报错，
D:\ros2prj\nav2_ws>colcon build

CMake Error at CMakeLists.txt:25 (find_package):
By not providing "Findturtlebot3_msgs.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"turtlebot3_msgs", but CMake did not find one.
Could not find a package configuration file provided by "turtlebot3_msgs"
with any of the following names:
turtlebot3_msgsConfig.cmake
turtlebot3_msgs-config.cmake
Add the installation prefix of "turtlebot3_msgs" to CMAKE_PREFIX_PATH or
set "turtlebot3_msgs_DIR" to a directory containing one of the above files.
If "turtlebot3_msgs" provides a separate development package or SDK, be
sure it has been installed.
