Yes, this is a known issue.

Unlike CUDA support, adding OptiX support requires us to include some specific NVIDIA headers.

Some people believe, that including the nvidia-optix-headers into our official build infringe copyright law. Despite this, I'm doing it in the blender builds of my home project:

https://build.opensuse.org/project/show/home:frispete:blender

You're free and welcomed to use this version, of course. I'm specifically interested in any issues using the Wayland platform.

Offending headers can be downloaded here: 
https://developer.download.nvidia.com/redist/optix/v7.4/OptiX-7.4.0-Include.zip

Although NVIDIA makes these headers publicly available for precisely this purpose, they have "overlooked" to adapt the copyright headers accordingly.

For a discussion with the Blender developers, see:
https://devtalk.blender.org/t/blender-2-8-cycles-optix-packaging/12533/12

Since these are C++ Headers containing inline code, one can argue, that this produces code (as being done by Stefan Brüns in that discussion).

If you have an idea, how to bug NVIDIA on that, let me know! 
Or you can find a way to get Stefan Brüns to relent.

Until that happens, I unfortunately have to close this issue as "WONTFIX".
