# The _cuda attribute set is a fixed-point which contains the static functionality required to construct CUDA package
|
|
# sets. For example, `_cuda.bootstrapData` includes information about NVIDIA's redistributables (such as the names
|
|
# NVIDIA uses for different systems), and `_cuda.lib` contains utility functions like `formatCapabilities` (which generate
|
|
# common arguments passed to NVCC and `cmakeFlags`).
|
|
#
|
|
# Since this attribute set is used to construct the CUDA package sets, it must exist outside the fixed point of the
|
|
# package sets. Make these attributes available directly in the package set construction could cause confusion if
|
|
# users override the attribute set with the expection that changes will be reflected in the enclosing CUDA package
|
|
# set. To avoid this, we declare `_cuda` and inherit its members here, at top-level. (This also allows us to benefit
|
|
# from import caching, as it should be evaluated once per system, rather than per-system and CUDA package set.)
