The example CMakeLists expected OB_SDK_LIB_NAME, which SDK v2.8.6 sets in the example scope but v2.4.3 (JetPack 6) does not — leaving a link to bare "ob::" that fails at generate time. The stock examples link ob::OrbbecSDK, so default to that when unset. Keeps the Nano's build working. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
