How to recompile opencv_traincascade (OpenCV 2.4)?

Question

I would like to know How to compile ONLY the program opencv_traincascade on macOS Sierra.

I have the source code of the traincascade (in the folder /opencv-2.4.13/apps/traincascade/). However, when I go to this folder and type on terminal:

cmake ..

It returns:

-- The C compiler identification is AppleClang 8.0.0.8000042
-- The CXX compiler identification is AppleClang 8.0.0.8000042

=> It does not understand the "ocv_check_dependencies"

Here is the CMakeLists.txt code:

  endif()

  install(TARGETS ${the_target} RUNTIME DESTINATION ${OPENCV_BIN_INSTALL_PATH} COMPONENT dev)
endif()

In addition, this question raised on my mind because I got stuck in the training process with -featureType LBP . When I train my face detector with LBP feature, it shows:

Andy-Chen:Temp Training macpro$ opencv_traincascade -data data -vec faces_15000-80000.vec -bg neg.txt -numPos 4000 -numNeg 10000 -numStages 10 -w 21 -h 24 -featureType LBP
===== TRAINING 0-stage =====
<BEGIN
POS count : consumed   4000 : 4000
NEG count : acceptanceRatio    10000 : 1

and then it keeps this status for several hours without any progress. However, if I train with HAAR feature, everything works fine.

Thus, I want to add some "cout" commands to the source code of traincascade so that I can see where the program gets stuck and then look for a solution or modify something to make it workable.

I look forward to hearing from your help. Thank you very much for your time.
