example_face_tracker expects dlib.a inside ofxFaceTracker2

[kylemcdonald]

After building everything from scratch i got an error with example_face_tracker expecting dlib.a inside ofxFaceTracker2/libs/dlib, but that libs/ folder doesn't exist. I fixed this by copying the libs/ folder from ofxDlib/libs.

example_face_tracker also expects a few files in the data folder. i copied them from elsewhere:

ibug_to_sfm.txt
sfm_3448_edge_topology.json
sfm_model_contours.json
sfm_shape_3448.bin
shape_predictor_68_face_landmarks.dat
