引用前提说明：

• 需要对应ABI的第三方so库，我这边已我自己编译完成的arm64-v8a的gmssl库为例，拥有libgmssl.so文件
• 需要第三方库提供的暴露so库中的方法的.h文件，一般会提供include文件夹内涵.h文件
• 在Android项目中已经进行了cxx连接，存在cpp目录以及目录下已经有cmakelists.txt文件

引用使用步骤：

1. 在项目或者模块的libs文件夹下新建对应ABI的文件夹我这边创建arm64-v8a文件夹并将so库放入其中

2. 将include文件夹复制到项目或者模块的src/main/cpp文件夹下

3. 在CMakeLists.txt中进行配置，需要添加的配置如下：

   #用于将LIB_DIR指向项目或者模块下的libs文件夹中
   set(LIB_DIR ${CMAKE_SOURCE_DIR}../../../../libs/arm64-v8a)

4. #添加gmssl库 这边可以替换为你们自己需要添加的第三方so库的名称不包含lib和.so
   add_library(gmssl SHARED IMPORTED)
   #设置添加方式为本地添加并将路径指向libgmssl.so
   set_target_properties(gmssl PROPERTIES IMPORTED_LOCATION ${LIB_DIR}/libgmssl.so)

5. #向当前项目或者模块添加第三方库的include目录，使之后在自己的cpp文件中能引用第三方库
   target_include_directories(SIKEncrypt PRIVATE ${CMAKE_SOURCE_DIR}/include)

6. #在项目或者模块中引用gmssl库
   target_link_libraries( # Specifies the target library.
          SIKEncrypt
   
          # Links the target library to the log library
          # included in the NDK.
   
          gmssl
          ${log-lib})

7. 下面贴出完整的CMakeLists.txt用于参考

   
   # 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 3.22.1)
   
   # Declares and names the project.
   
   project("SIKEncrypt")
   # 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.
          SIKEncrypt
   
          # Sets the library as a shared library.
          SHARED
   
          # Provides a relative path to your source file(s).
          SIKEncrypt.cpp)
   # Set the path to the directory containing the prebuilt libraries
   set(LIB_DIR ${CMAKE_SOURCE_DIR}../../../../libs/arm64-v8a)
   
   add_library(gmssl SHARED IMPORTED)
   set_target_properties(gmssl PROPERTIES IMPORTED_LOCATION ${LIB_DIR}/libgmssl.so)
   
   target_include_directories(SIKEncrypt PRIVATE ${CMAKE_SOURCE_DIR}/include)
   # 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.
          SIKEncrypt
   
          # Links the target library to the log library
          # included in the NDK.
   
          gmssl
          ${log-lib})
   

到此第三方so库算是添加完成了并可以正常使用了，如果对你有什么帮助的话，麻烦点个赞？感谢！
