Trouble building with CUDA 11.1 - CUDA_nppicom_LIBRARY not found

[jknick]

Is there a dependency on CUDA 10.2 for this wrapper?

When trying to build with colcon for Ubuntu 20.04 with CUDA 11.1 we're hitting this error:

--- stderr: zed_components

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
CUDA_nppicom_LIBRARY (ADVANCED)
linked by target "zed_camera_component" in directory /home/kanke/ros2_example_ws/src/zed-ros2-wrapper/zed_components

Failed   <<< zed_components [1.72s, exited with code 1]

Summary: 5 packages finished [3.42s]
1 package failed: zed_components
1 package had stderr output: zed_components
2 packages not processed

In digging a little bit it seems that libnppicom.so is no longer part of CUDA, but also I don't see where the reference to this is coming from as it doesn't seem to be reference anywhere in this repo.

Any thoughts? Thanks!

I've applied this diff to my FindCUDA and it now seems to compile:

Thanks, Rayman!

The same question. I'm using Ubuntu18.04, Cuda11.0, SDK3.5 and ros2-eloquent.

@jknick @Rayman Do you solve it?

@Kismetzc I suppose this is the solution that they found: https://github.com/stereolabs/zed-ros2-wrapper/issues/25#issuecomment-799383330

@Kismetzc I suppose this is the solution that they found: #25 (comment)

Yeah. Does this mean I should update my cmake version？

[Myzhar]

Yes, it can solve the issue

[Kismetzc]

Yes, it can solve the issue

THX！I will try right now.

[Kismetzc]

Thank you all !!! I have solved this problem.

The solution works, so I close the issue
