Use CMake's standard package discovery output and FeatureSummary instead of custom status messages, so configuration reports package availability, versions, and failure reasons consistently. Rename Ceres feature controls to use the WITH_ prefix to group them consistently and eliminate inconcistent naming. Remove retrospective cache updates so package discovery preserves caller-provided values and avoids unnecessary side effects. Fixes #876 Change-Id: Ib6e40d56a0ea89b292fe34554777593ffda95f42
