When building with the instructions in https://github.com/chrxh/alien/issues/100#issuecomment-2308899636, I get the following error.

CMake Error at /usr/share/cmake/Modules/Internal/CMakeCUDAFindToolkit.cmake:104 (message):
  Failed to find nvcc.

  Compiler requires the CUDA toolkit.  Please set the CUDAToolkit_ROOT
  variable.
Call Stack (most recent call first):
  /usr/share/cmake/Modules/CMakeDetermineCUDACompiler.cmake:85 (cmake_cuda_find_toolkit)

Building branch v4.10.2 or with the instructions in the README also fails. building with cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_COMPILER=gcc-11 -DCMAKE_CXX_COMPILER=g++-11 -DCMAKE_CUDA_COMPILER=/opt/cuda/bin/nvcc, I get

I am using the Arch CUDA package.

Have you checked archlinux wiki for cuda? What is the output of nvidia-smi in your case?
