Doing the source install
Problem
1) missing dynamixel_sdk
2) Colcon build should occur in turtlebot3_ws directory
not in turtlebot3_ws/src
Evidence
$ colcon build --symlink-install
Starting >>> turtlebot3_msgs
Starting >>> turtlebot3_description
Starting >>> turtlebot3_cartographer
Starting >>> turtlebot3_navigation2

CMake Error at CMakeLists.txt:19 (find_package):
By not providing "Finddynamixel_sdk.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"dynamixel_sdk", but CMake did not find one.
Could not find a package configuration file provided by "dynamixel_sdk"
with any of the following names:
dynamixel_sdkConfig.cmake
dynamixel_sdk-config.cmake
Add the installation prefix of "dynamixel_sdk" to CMAKE_PREFIX_PATH or set
"dynamixel_sdk_DIR" to a directory containing one of the above files. If
"dynamixel_sdk" provides a separate development package or SDK, be sure it
has been installed.
Solutions
1)
$ sudo apt-get install ros-dashing-dynamixel-sdk*
2)
$ cd ..
Investigation: I think this is what happed
In January 18, 2021 instructions the dynamixel-sdk was built from the following commands:
$ wget https://raw.githubusercontent.com/ROBOTIS-GIT/turtlebot3/ros2/turtlebot3.repos
$ vcs import src < turtlebot3.repos
The new instructions from February 16, 2021 do not follow the above steps. It has these steps
$ git clone -b dashing-devel https://github.com/ROBOTIS-GIT/turtlebot3_msgs.git
$ git clone -b dashing-devel https://github.com/ROBOTIS-GIT/turtlebot3.git
$ colcon build --symlink-install
