Hello, while trying to compile ETK with CarpetX I get the following error:  

```
COMPILING CarpetX/PDESolvers/src/pdesolvers.cxx
/gpfs/home/uib/uib416720/ETK2024/CarpetX/Cactus/arrangements/CarpetX/Arith/src/spvect.hxx(169): error: calling a __host__ function from a __host__ __device__ function is not allowed

Important to know is that I’m compiling with CUDA and added the necessary modifications to my cfg file \(attached\).  
These are also the modules I’m using while compiling:    
  
- oneapi/2023.2.0 which includes: intel/2023.2.0, impi/2021.10.0, mkl/2023.2.0, and ucx/1.15.0  
- cuda/12.2
