Hey @AndreV84, I am experiencing the same error but using ROS2 Galactic in Ubuntu Bionic. The weird thing is that it was working before. Did you find any solution?

[Myzhar]

ROS2 Humble is not yet supported by the ROS2 wrapper. We will work on this feature in the new few weeks.
ROS2 Galactic will not be officially supported because it's not an LTS version and the EOL date is very close.
For more information:
https://docs.ros.org/en/galactic/Releases.html

[Myzhar]

Upgrading a Jetson board to a version of the Operating System not officially supported is not a good practice and the final result will be an unstable machine.
In this particular case, Jetpack 5.0.1 is based on Ubuntu 20.04 and it should not be upgraded to Ubuntu 22.04 because Nvidia does not provide drivers for this version and on our side, we do not provide a ZED SDK version for Ubuntu 22.04 running on Jetson.
To use ROS2 Humble on Jetson the good practice is to compile it from the source or use a Docker container.

[Myzhar]

I close the issue because it's not valid.

@AndreV84 I fixed the issue by downgrading CMake to version 3.23.2. Apparently ament_cmake has an issue with CMake 3.24+

See: ament/ament_cmake#396

@Myzhar
How do you add the wrapper into existing ros humble container [nvblox nav nvblox humble provided by nvidia] ?
from running container terminal it won't appear that sdk file installation results in satisfaction of requirements for the wrapper as it would fail with

  Could not find a package configuration file provided by "ZED" (requested

  Add the installation prefix of "ZED" to CMAKE_PREFIX_PATH or set "ZED_DIR"

zed sdk is already installed systemwide
trying to install it from container gets through some of steps but will throw

The error means that you have not installed the ZED SDK.

PS please never post in a closed issue.
If it's a bug kindly create a new issue.
If it's a question or a support request please ask on the Stereolabs forum

but it is not a closed issue as far as I am concerned:
I am still not able to run the zed ros wrapper since " Aug 20" when it was emerged
