I'm trying to build OpenCv4Android on OSX using the instructions found here.
They seem to be slightly out of date, as they reference the old location of the git respository, and say I should be doing this:
cd opencv/android
sh ./scripts/cmake_android.sh
Whereas in the current repository, scripts live in platforms/scripts, so I'm doing this:
sh /platforms/scripts/cmake_android_arm.sh
However, that produces the following error:
➜ opencv git:(master) ✗ ./platforms/scripts/cmake_android_arm.sh
CMake Error at platforms/android/android.toolchain.cmake:694 (message):
Could not find any working toolchain in the NDK. Probably your Android NDK
is broken.

Despite the error message, I'm using a clean installation of the NDK and have it set on $ANDROID_NDK.
Any ideas what I'm doing wrong?
