How to recompile opencv_traincascade (OpenCV 2.4)? - macos

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
-- Check for working C compiler: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc
-- Check for working C compiler: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc -- works

CMake Warning (dev) in CMakeLists.txt:
No cmake_minimum_required command is present. A line of code such as

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.
