如何在AAR中引用SO文件？

Question

aar文件中有一些SO文件，我希望在我的项目中使用这些文件。我应该如何写CMakeList.txt和build.gradle文件？

build.gradle

dependencies {
    implementation 'example:example:1.7.11' // <--- SO file exists in this dependency
}

AAR文件结构

│  AndroidManifest.xml
│  classes.jar
│  R.txt
│
├─arm64-v8a
├─armeabi-v7a
├─jni
│  ├─arm64-v8a
│  │      libAK.so
│  │      libAKCompat.so
│  │
│  ├─armeabi-v7a
│  │      libAK.so   <--- Suppose I need this document
│  │      libAKCompat.so
│  │
│  ├─x86
│  │      libAK.so
│  │
│  └─x86_64
│          libAK.so

├─x86
└─x86_64
