Question

I am trying to install the ros-perception/pointcloudtolaserscan package but I am getting the following error during compilation:

--- stderr: pointcloud_to_laserscan                         
CMake Error at CMakeLists.txt:15 (add_library):
  Target "laserscan_to_pointcloud" links to target
  "rclcpp_components::component" but the target was not found.  Perhaps a
  find_package() call is missing for an IMPORTED target, or an ALIAS target
  is missing?

Please ensure you have installed the ROS Galactic completely. I simply go with sudo apt install ros-galactic-desktop
Make sure you are using the galactic branch of the repository.

I am able to compile it peacefully. Please see the steps below:

ravi@dell:~/ros2_ws$ cd src/
ravi@dell:~/ros2_ws/src$ source /opt/ros/galactic/setup.bash
ravi@dell:~/ros2_ws/src$ git clone --branch galactic https://github.com/ros-perception/pointcloud_to_laserscan.git
