wdk-build find_top_level_cargo_manifest() walks UP from OUT_DIR to the first ancestor with a Cargo.lock; the relocated CARGO_TARGET_DIR=C:\\t\\drvws hid the workspace lock (ancestors C:\\t, C:\\ have none) -> the "Cargo.lock should exist" panic. Drop the override; the driver deps have no deep CMake crates so the in-tree target stays under MAX_PATH. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
