How to add multiple cmake target to android ndk project

Question

So I started an android ndk project, and added a new module another_lib in addition to the native-lib that comes with the new project, I have a cmakelists.txt file in as shown and the content is:

cmake_minimum_required(VERSION 3.4.1)
add_subdirectory(another_lib)
add_subdirectory(native_lib)

and for each subdirectory, i have defined a build target. then in my build.gradle i have

   externalNativeBuild {
        cmake {
            path "src/main/cpp/CMakeLists.txt"
        }
    }

However, when I built the project, it only builts native_lib. Did i miss anything to add my own module to build?

It is the issue that android cannot create static lib unless it is added in the build.gradle file, for me I need to add line:

externalNativeBuild {
    cmake {
        ...
        targets "native-lib", "anotherlib"
    }
}
