I managed to build OpenCV 2.4.9 for java following the online instructions.
However I am unable to build for Android
I am using OSX Yosemite, CMake 3.0.2, OpenCV 2.4.9.
The output I get is the following:
======

I tried setting both: export ANDROID_NDK=~/android-ndk-r8e and export ANDROID_STANDALONE_TOOLCHAIN=~/android-toolchain
but both give same error. Any clues to what is causing this? Bad version of CMake?
