Research direction
Start by running make and inspect Makefile line 21 alongside libfacedetect-example.cpp, where the four undefined detection symbols are referenced. Trace the build inputs for those symbols and confirm the example links successfully, then verify how the 68-keypoint detection path is intended to be used.
