Hi,

I have tried to compile mumax3 on Ubuntu. I have followed the installation instructions of "https://github.com/mumax/3", but I have not been lucky:

`cgo-gcc-prolog: In function ‘_cgo_c21ce16ee817_Cfunc_cuDeviceComputeCapability’:
cgo-gcc-prolog:56:2: warning: ‘cuDeviceComputeCapability’ is deprecated [-Wdeprecated-declarations]

I have Cuda 11.5 installed (diver version 495.29.05).

thanks
