error: the cuda backend is not available!

[SolomonIxanSmith]

I installed ebsynth and the cuda toolkit. Right now it gives me the error above when I try to set the backend to CUDA. Anyone have any luck getting around this? I had to change the nvcc compiler options to compute_52 instead of compute_30 as others have pointed out but compilation worked and gave no errors.
Is there a version of CUDA that I should be using? Should I even bother or is the performance increase not worth it?

Ubuntu 21.04
GTX 970
Installed version of cuda is: cuda_11.2.r11.2

yes, when enable cuda, the performance improves a lot.
