Could you help ? Thx

You didn't do the 2nd step in the instructions

Change the OpenCV Android SDK library path in Android.mk file to your my/path/to/OpenCV-android-sdk/sdk/native/jni/OpenCV.mk

You need to download the OpenCV Android SDK (which was too big to track in this repo) and then change that line from

/home/fricke/OpenCV-android-sdk/sdk/native/jni/OpenCV.mk which was my personal path to the path for you where you have it on your machine

ALSO looks like you are on windows so MAKE SURE you either do / for the slashes in the path inside that Android.mk file
