Hard requirement for cuda?

[GloriousEggroll]

I'm trying to build this as an rpm package for fedora, but it seems to have hard coded rpaths that require cuda:

ERROR   0002: file '/usr/lib64/obs-plugins/obs-backgroundremoval/libonnxruntime.so.1.17.1' contains an invalid rpath '/usr/local/cuda-11.8/lib64' in [$ORIGIN:/usr/local/cuda-11.8/lib64:]
ERROR   0010: file '/usr/lib64/obs-plugins/obs-backgroundremoval/libonnxruntime.so.1.17.1' contains an empty rpath in [$ORIGIN:/usr/local/cuda-11.8/lib64:]
ERROR   0002: file '/usr/lib64/obs-plugins/obs-backgroundremoval/libonnxruntime_providers_cuda.so' contains an invalid rpath '/usr/local/cuda-11.8/lib' in [/usr/local/cuda-11.8/lib:]
ERROR   0010: file '/usr/lib64/obs-plugins/obs-backgroundremoval/libonnxruntime_providers_cuda.so' contains an empty rpath in [/usr/local/cuda-11.8/lib:]

Does this absolutely require cuda to function properly? I didn't see any mention of cuda as a hard requirement in the readme.

Nevermind figured it out.

The bundled onnxruntime libraries with the default build options from https://github.com/occ-ai/obs-backgroundremoval/pull/581 force cuda rpaths.

There's a few things to fix. --

1. I was messing with the ROCM PR here:

https://github.com/occ-ai/obs-backgroundremoval/pull/545

And without the CMakeList changes there for using system onnxruntime it would not detect onnxruntime on my system even though I had onnxruntime-devel installed. So, I recommend porting that portion of that patch over.

2. After that, I enabled:

-DUSE_SYSTEM_ONNXRUNTIME=ON \

And build requirements:

BuildRequires: onnxruntime-devel

And requirements:

Requires: onnxruntime

However, that kept wanting to use:

OrtSessionOptionsAppendExecutionProvider_Tensorrt

Which of course relies on cuda, so I also did:

-DDISABLE_ONNXRUNTIME_GPU=ON \

That allowed it to fully work and build on Fedora via my spec sheet.

Here's the relevant parts of my spec sheet:

Name:           obs-studio-plugin-backgroundremoval

This should be enough for a clean Fedora rpm build without relying on cuda or rocm
