How to link multiple C++ cmake project to a Android Studio/gradle project?

Issue

I have two separate native C++ project built with NDK and using in a single Android application. I have linked one of them to the project in Android project via right click and select "Link C++ Project with Gradle".

This operation added following text to build.gradle.

externalNativeBuild {
    cmake {
        path file('src/main/cpp/CMakeLists.txt')
    }
}

How can I added another one to the application? Note I cannot merge those two C++ project. I want to debug C++ code in Android Studio, not just compile it.

Environment: Android Studio 3.4, gradle-4.10.1

Solution

link them to two library modules instead and add this there twice:

externalNativeBuild {
    cmake {
        path file('src/main/cpp/CMakeLists.txt')
    }
}

sourceSets {
    main {
        jni.srcDirs = ["src/main/cpp"]
    }
}

so it will load two different CMakeLists.txt.
