Building OpenCV 2.4 for arm64-v8a or x86_64 (CMake / make)

edit

I tried to compile OpenCV 2.4.11 for arm64-v8a, but there is only one .so file I got after building in my_build\lib\arm64-v8a folder: libopencv_info.so (others are .a)

What did I do wrong?

It should also have built libopencv_java.so & libnative_camera_r*.so files, but it haven't

cmake parameters:

cd opencv\platforms
mkdir build_android_arm
cd build_android_arm
cmake -G "MinGW Makefiles" -DCMAKE_TOOLCHAIN_FILE=..\android\android.toolchain.cmake  -DANDROID_ABI="arm64-v8a"  -DWITH_TBB=ON  -DINSTALL_ANDROID_EXAMPLES=ON  -DANDROID_NATIVE_API_LEVEL=16 -D WITH_OPENCL=OFF -D WITH_OPENCL_SVM=OFF -D WITH_OPENCLAMDFFT=OFF -D WITH_OPENCLAMDBLAS=OFF ..\.. 
make
