Summary of Changes

Hello @cyx-6, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the build process for the torch_c_dlpack_ext addon by introducing a dedicated Windows batch script for AOT wheel generation. It addresses critical Windows-specific build challenges, such as properly handling file paths with spaces and ensuring correct linking of CUDA libraries, thereby enabling robust and automated wheel creation for various PyTorch versions on the Windows platform.

Highlights

• New Windows Build Script: A new batch script (build_aot_wheels.bat) has been added to automate the building of Ahead-Of-Time (AOT) wheels for the torch_c_dlpack_ext addon on Windows, supporting various PyTorch versions.
• Improved Include Path Handling: The build utility now correctly handles include paths on Windows, specifically by quoting paths that contain spaces and ensuring proper drive letter formatting, preventing potential build failures.
• Corrected CUDA Linker Flags for Windows: The linker flags for CUDA-enabled builds on Windows have been updated to explicitly include torch_cuda.lib and c10_cuda.lib, resolving linking issues when building with CUDA support.

Code Review

This pull request adds a Windows batch script to build torch_c_dlpack_ext wheels, along with necessary adjustments in the Python build utility. The changes in the Python script for handling Windows paths and CUDA libraries are correct. The new batch script is functional, but I've identified a few areas for improvement to enhance its robustness and maintainability. Specifically, I'm suggesting changes to handle directory creation idempotently, remove an unnecessary package dependency for Windows, and refactor a section for better readability.
