May 2025 summary for microsoft/vcpkg: Implemented two high-impact changes that improve reliability and usability. First, LibTorch: removed CUDA from default features to simplify installation; GPU support remains opt-in. Commit 52d831c88b7687d6e176296787ada76b1b4419b1. Second, GTest Port: fixed a debug build failure by applying the pkgconfig replacement only to release builds, aligning with static linking expectations. Commit e73873a22dd8758fdf50e6d5bfd6b8d17bdf231b. Impact: reduces CI failures and user setup friction, improves packaging consistency, and boosts maintainability. Skills demonstrated: build-system tuning (CMake/pkgconfig), feature flag management, debugging for cross-compiled scenarios, and collaboration across maintainers.
