Failed to build with ROS2 Bouncy release #30

Tried to build this package with the RO2 Bouncy release but got blocked. Here are the steps and logs:

$ source <path/to/ros2-linux>/local_setup.bash
$ mkdir -pv ~/ros2_ws/src
$ cd ~/ros2_ws/src
$ git clone https://github.com/ros-perception/depthimage_to_laserscan.git
$ git clone https://github.com/ros-perception/vision_opencv.git
$ cd ~/ros2_ws
$  colcon build --symlink-install --packages-select image_geometry depthimage_to_laserscan

--- stderr: depthimage_to_laserscan                         
CMake Error at CMakeLists.txt:6 (find_package):
  By not providing "Findcatkin.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "catkin", but
  CMake did not find one.

  Could not find a package configuration file provided by "catkin" with any
  of the following names:

    catkinConfig.cmake
    catkin-config.cmake

  Add the installation prefix of "catkin" to CMAKE_PREFIX_PATH or set
  "catkin_DIR" to a directory containing one of the above files.  If "catkin"
  provides a separate development package or SDK, be sure it has been
  installed.

Failed   <<< depthimage_to_laserscan    [ Exited with code 1 ]

Summary: 1 package finished [6.76s]
  1 package failed: depthimage_to_laserscan
  1 package had stderr output: depthimage_to_laserscan

Notice, vision_openv/image_geometry is need as it must be built before building the depthimage_to_laserscan package.

This fails to compile because you are using the ROS1 version of these packages. You need to use the ros2 fork of depthimage_to_laserscan and the ros2 branch of the vision_opencv repository. The list of repositories for the ROS 2 core can be found here and the higher level packages (Linux only ATM) can be found here.

As we recommend to ask questions on answers.ros.org I'm going to close this ticket. If you face any more issue please ask a question on answers.ros.org and if possible comment here with the link for future readers. HTH
