Как связать стороннюю статическую библиотеку с недавно созданным проектом cmake?

Question

У меня есть статическая библиотека, созданная для архитектуры arm64-v8a.Мне нужно написать оболочку для вызова одной из основных функций статической библиотеки и передать результат в код Java.Для этого я создал новый нативный проект в студии android и добавил статическую библиотеку в папку cpp как mylib.a.Я пытался добавить эту библиотеку в CMakeLists.txt, но проект не компилируется.Ниже мой CMakeLists.txt:

# For more information about using CMake with Android Studio, read the
# documentation: https://d.android.com/studio/projects/add-native-code.html

# Sets the minimum version of CMake required to build the native library.

cmake_minimum_required(VERSION 3.4.1)

# Creates and names a library, sets it as either STATIC
# or SHARED, and provides the relative paths to its source code.
# You can define multiple libraries, and CMake builds them for you.
# Gradle automatically packages shared libraries with your APK.

add_library( # Sets the name of the library.
        native-lib

        # Sets the library as a shared library.
        SHARED

        # Provides a relative path to your source file(s).
        native-lib.cpp)

add_library( # Sets the name of the library.
        mylib

        # Sets the library as a shared library.
        STATIC

        # Provides a relative path to your source file(s).
        mylib.a)

# Searches for a specified prebuilt library and stores the path as a
# variable. Because CMake includes system libraries in the search path by
# default, you only need to specify the name of the public NDK library
# you want to add. CMake verifies that the library exists before
# completing its build.

find_library( # Sets the name of the path variable.
        log-lib

        # Specifies the name of the NDK library that
        # you want CMake to locate.
        log)

# Specifies libraries CMake should link to your target library. You
# can link multiple libraries, such as libraries you define in this
# build script, prebuilt third-party libraries, or system libraries.

target_link_libraries( # Specifies the target library.
        native-lib

        # Links the target library to the log library
        # included in the NDK.
        ${log-lib}
        ${mylib})

Я новичок в CMake.Пожалуйста, помогите мне связать статическую библиотеку с моей общей библиотекой.

CMake обращается к предварительно собранным библиотекам через импортированную библиотеку: https://cmake.org/cmake/help/latest/command/add_library.html#imported-libraries

add_library(mylib
    STATIC
    IMPORTED
    mylib.a)
