CMake Error when building image_publisher

[kevinkeryk]

Installed ROS 2 packages under Ubuntu 20.04 along with Vitis 2021.2 tools installed following these instructions: http://docs.ros.org/en/rolling/Installation/Ubuntu-Install-Debians.html

Talker and listener examples are working but now when I follow the beta install directions for KRS: https://github.com/vmayoral/KRS/blob/beta/sphinx/source/docs/install.md

I am running into the following fatal error during the colcon build --merge-install step:

CMake Error at CMakeLists.txt:13 (find_package):
  By not providing "Findament_cuda.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "ament_cuda", but CMake did not find one.

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

    ament_cudaConfig.cmake
    ament_cuda-config.cmake

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

Failed   <<< image_publisher [2.51s, exited with code 1]

I tried the solution mentioned in https://github.com/Xilinx/KRS/issues/35 since they look very similar, but still seeing the issue.

This causes other package builds to abort as well. Has anyone else run into this issue?

@kevinkeryk I think you have a mix in your workspace from previous iterations. The package that's complaining is within https://github.com/Xilinx/KRS/blob/main/krs_rolling.repos#L19-L22, note it's using the beta branch. Are you by chance using the ros2 branch?

• ros2: uses ament_cuda https://github.com/ros-acceleration/image_pipeline/blob/ros2/image_publisher/CMakeLists.txt#L13 (that's what I'm working on right now, cutting edge, you should not be using this)
• beta: no ament_cuda https://github.com/ros-acceleration/image_pipeline/blob/beta/image_publisher/CMakeLists.txt

Clean the whole workspace up and re-start (remove everything).

Okay, I cleaned up my workspace and started following this instead to move past this issue:
