my specs:
OS: arch
Kernel: 6.2.2-arch1-1
CUDA Version: 11.4
cmake version: 3.25.3

I am experiencing the exact same issue
(Maybe this is related to #174 ?)
You can try updating CUDA to the latest version 12.1 and see if anything changes
Also what version of gcc are you using?

[Dvd-Znf]

Found temporary solution for building xmrig-cuda:
Add the -DCUDA_ARCH=(Your compute capability) when using cmake
You can find out your "compute capability" by looking at the official tables provided by nvidia:
https://developer.nvidia.com/cuda-gpus#compute
For example, for my RTX 3050 i used -DCUDA_ARCH=75

However xmrig will still not work showing the message: "Driver does not support CUDA 12.1 API! Update your nVidia driver!"
Even though i am using the latest available drivers, this seems to be an issue with xmrig support for certain drivers

[materia-nigra]

The solution above did the trick!
As an aside comment, for those trying to compile on ArchLinux, the process is the same as indicated on https://xmrig.com/docs/miner/build/ubuntu, except for different paths: -DCUDA_LIB=/opt/cuda/lib64/stubs/libcuda.so -DCUDA_TOOLKIT_ROOT_DIR=/opt/cuda

Another way is to install nvidia-beta (530+) on Arch.

gcc 13 did not seem to work.

might need to roll back to 12.

see #138 , I presented a solution using "spack" to build with another gcc version.
