USE_CUDA is a Ceres cache STRING (default "default" = auto-detect), not an option(), so a plain SET was shadowed by the cache default and CUDA got enabled on MSVC. Force it OFF in the cache instead. Also drop two dead settings: MINIGLOG (Ceres uses abseil logging now, no longer referenced) and EIGENSPARSE ON (already Ceres' default). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
