I recently had a similar problem getting the modules to build on Windows 10 with UE 5.1. Attempting to build the .sln manually with Visual Studio 2022 led me to discover that StereolabsBuild.cs:26 is looking for the CUDA installation through the environment variable CUDA_PATH but the CUDA v12.1 installation set the environment variable CUDA_PATH_V12_1. Setting the System environment variable CUDA_PATH to the same value that was set for CUDA_PATH_V12_1 allowed me to successfully build the modules. This approach may solve your problem.

Hi @maxwaba, The plugin is compatible only with UE5.1 for now, we'll be porting it to UE5.2 in the near future. Do you have any error along with the failing rebuild? As @sdetwiler pointed out, what version of CUDA are you using?

@sdetwiler thanks for pointing this out, we'll fix this shortly.

the environment variable CUDA_PATH where do we find this file StereolabsBuild.cs to change the CUDA_PATH for required version, the error I am getting right now is as follows,

I am using UE5.1.1 and cuda 12.1

The file itself should not be the issue, but it is located here (trace back from your pulled repo): https://github.com/stereolabs/zed-UE5/blob/main/Plugins/Stereolabs/Source/Stereolabs/Stereolabs.Build.cs

Please check that the environment variable "CUDA_PATH"'s value is set to your CUDA 12.1 install, and if that is not the case, edit it to the path you need, restart your computer, and try again.

I am getting the same error after changing the path environment I am using windows 11pro at the moment, would that be a problem ?
