1# The _cuda attribute set is a fixed-point which contains the static functionality required to construct CUDA package
2# sets. For example, `_cuda.bootstrapData` includes information about NVIDIA's redistributables (such as the names
3# NVIDIA uses for different systems), `_cuda.lib` contains utility functions like `formatCapabilities` (which generate
4# common arguments passed to NVCC and `cmakeFlags`), and `_cuda.fixups` contains `callPackage`-able functions which
5# are provided to the corresponding package's `overrideAttrs` attribute to provide package-specific fixups
6# out of scope of the generic redistributable builder.
7#
8# Since this attribute set is used to construct the CUDA package sets, it must exist outside the fixed point of the
9# package sets. Make these attributes available directly in the package set construction could cause confusion if
10# users override the attribute set with the expection that changes will be reflected in the enclosing CUDA package
11# set. To avoid this, we declare `_cuda` and inherit its members here, at top-level. (This also allows us to benefit
12# from import caching, as it should be evaluated once per system, rather than per-system and CUDA package set.)
