can't build gazebo_ros2_control after building ros2_control
ros2_control is installed and built but gazebo_ros2_control fails:
:~/ws_ROS2/gazebo_ros2_control$ colcon build
Starting >>> gazebo_ros2_control
--- stderr: gazebo_ros2_control
CMake Error at CMakeLists.txt:6 (find_package):
By not providing "Findcontroller_manager.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"controller_manager", but CMake did not find one.
Could not find a package configuration file provided by
"controller_manager" with any of the following names:
controller_managerConfig.cmake
controller_manager-config.cmake
Add the installation prefix of "controller_manager" to CMAKE_PREFIX_PATH or
set "controller_manager_DIR" to a directory containing one of the above
files. If "controller_manager" provides a separate development package or
SDK, be sure it has been installed.

What else to try?
Which packages do you have installed in your system or in your workspace? controller-manager should appear in a colcon list on the workspace or you will need to install it as a binary package.
