Technically the CUDA 13.2 comment isn't accurate yet but it will be after #51210

Comment thread ports/itk/portfile.cmake

if(NOT DEFINED ENV{CUDAARCHS})
# ITK defaults to 52 which is no longer supported in CUDA 13.2 as used in vcpkg's test lab.
set(ENV{CUDAARCHS} 75)

Note that 75 is Turing (that is, the oldest hardware supported by NVIDIA's current drivers)

See https://docs.nvidia.com/cuda/cuda-programming-guide/05-appendices/compute-capabilities.html -- all the tables start at 7.5.
