Setting up ROS2 with a pmd 3D Camera
Hi!
I was following this tutorial. https://www.youtube.com/watch?v=2d3qm...
At 5:33 in the tutorial, you have to execute
'colcon build --cmake-args "-DCMAKE_PREFIX_PATH=/home/madas/Documents/Jungreuthmayer/libroyale-5.4.0.2112-LINUX-x86-64Bit/lib/cmake"'
I always get the following error-output:
madas@madas-ThinkPad-T460s:~/Documents/Jungreuthmayer/Tutorials/pmdCamera/ros2_ws$ colcon build --cmake-args "-DCMAKE_PREFIX_PATH=/home/madas/Documents/Jungreuthmayer/libroyale-5.4.0.2112-LINUX-x86-64Bit/lib/cmake"
Starting >>> royale_in_ros2

One problem could be that i my Ros2-Version is "Humble". However, in the tutorial, version "Foxy" is used.
Also, i have noticed that in the libroyale-folder, i don't have a share-folder as shown in the tutorial. This is probably due to an older version in the tutorial. (Note: libroyale is not specific to Ros) In my case, the appropriate cmake-file can be found in libroyale-5.4.0.2112-LINUX-x86-64Bit/lib/royaleConfig.cmake.
In the tutorial, the file has a slightly different name: "royale-config.cmake".
Maybe, the solution is to change some specifications in the CMakeLists.txt-file in the sampleROS2-folder. (e.g. include directories). Maybe, the package.xml has to be adjusted too.
The file that can't be found is a file which is contained in the ros2-installation-folder. For some reason, it can't be found. I am also quite sure, that there are more files which can't be found but this is the first one so build-process stops here.
I would be glad about any help.
BR, Jakob
