I am using Mac OS X 10.11.6. The packages for opencv_contrib I git cloned from github repository. And opencv package I took from the official website. So they should both be up to date.
My version of g++ is
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 7.3.0 (clang-703.0.31)
Target: x86_64-apple-darwin15.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
I can build OpenCV independently fine on my machine but when I include opencv_contrib. It got stuck when make, when it tries to
$ cmake -DOPENCV_EXTRA_MODULES_PATH=/Users/ssabpisa/tmp/opencv_contrib/modules ../
CMake Warning at cmake/OpenCVPackaging.cmake:23 (message):
