Question

我有一个针对arm64-v8a架构构建的静态库。我需要编写一个包装程序来调用静态库的主要功能之一，并将结果传递给Java代码。为此，我在android studio中创建了一个新的本机项目，并在cpp文件夹中将静态库添加为mylib.a。我试图在CMakeLists.txt中添加此库，但该项目未编译。以下是我的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})

我是CMake的新手。请帮助我将静态库与共享库链接。

CMake通过导入的库访问预构建的库：https://cmake.org/cmake/help/latest/command/add_library.html#imported-libraries

...queryEnding(atValue: input + "\u{f8ff}")... // <-- Also note that the unicode character is escaped here

如何将第三方静态库与新创建的cmake项目链接？
