CMake Error at CMakeLists.txt:18 (find_package):
By not providing "Findament_cmake.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"ament_cmake", but CMake did not find one.
Could not find a package configuration file provided by "ament_cmake" with
any of the following names:
ament_cmakeConfig.cmake
ament_cmake-config.cmake
Add the installation prefix of "ament_cmake" to CMAKE_PREFIX_PATH or set
"ament_cmake_DIR" to a directory containing one of the above files. If
"ament_cmake" provides a separate development package or SDK, be sure it
has been installed.

Troubleshooting_4
今回利用させていただいたDockerイメージでは、VNCからターミナルを開くとRootでログインできない。
また、ROSのワークスペースが /root配下にあるため、source ~/turtlebot3_ws/install/setup.bash を実行できない。
VSCodeでこのDockerにShellをアタッチするとRootでログインできるので、ここでRootパスワードを変更した。
sudo passwd root

[ERROR] [gzclient-2]: process has died [pid 18100, exit code -6, cmd 'gzclient'].
権限の問題っぽいので、
chmod 777 /root
をしたうえで、Rootを抜けて一般ユーザでturtlebot3_wsに移動して、
export TURTLEBOT3_MODEL=burger
source /root/turtlebot3_ws/install/setup.bash
をやってからリトライしたら正常にGazeboが起動した。
同様の手順をほかのTerminalでも実行したところ、正常にTeleopできた。
