// We always create the cuda tag when included, but we only mark it as a valid tag when
// VISKORES_ENABLE_CUDA is true. This is for easier development of multi-backend systems.
//
// We usually mark the Cuda device as valid if VISKORES_ENABLE_CUDA even if not compiling with Cuda.
// This is because you can still call a method in a different translation unit that is compiled
// with Cuda. However, if VISKORES_NO_ERROR_ON_MIXED_CUDA_CXX_TAG is set and we are not compiling with
// Cuda, then the device is marked invalid. This is so you can specifically compile CPU stuff even
// if other units are using Cuda.
