ilSrSSKrSSKrSSKrSrS\S\S\4Sjr\RS\S-4Sj5r g) aCentralized CUDA environment variable handling. This module defines the canonical search order for CUDA Toolkit environment variables used throughout cuda-python packages (cuda.pathfinder, cuda.core, cuda.bindings). Search Order Priority: 1. CUDA_PATH (higher priority) 2. CUDA_HOME (lower priority) If both are set and differ, CUDA_PATH takes precedence and a warning is issued. Important Note on Caching: The result of get_cuda_path_or_home() is cached for the process lifetime. The first call determines the CUDA Toolkit path, and all subsequent calls return the cached value, even if environment variables change later. This ensures consistent behavior throughout the application lifecycle.
