Build is always failing with a linker error when trying to build OpenCV sdk with BUILD\_ANDROID\_PROJECTS enabled and ANDROID\_ABI=arm64-v8a

Where can I find information regarding which sdk, ndk versions compatible with each opencv releases?

```auto
[776/776] Linking CXX shared library jni/arm64-v8a/libopencv_java4.so
FAILED: jni/arm64-v8a/libopencv_java4.so  
....   
lib/arm64-v8a/libopencv_imgcodecs.a: error adding symbols: Archive has no index; run ranlib to add one
clang++: error: linker command failed with exit code 1 (use -v to see invocation)
ninja: build stopped: subcommand failed.

```
