官方arkts 引入第三方so库 缺胳膊少腿的，经过实践完成了so库的导入
1，当然要有一个so ，新建一个c++工程，不要修改，直接编译或者运行
在build下的outputs中拿到hap包，其中有so

2.解压hap, 拿到libs文件夹，检查一下里面有没有so
然后放到你的项目entry下

下面的libentry.so是运行后出现的

3.将CPP复制到main目录下面

你没看错CMakeLists.txt也要当然里面要修改，目的是找到so库怎么修改等后面讲，咱先不放CMakeLists.txt

4.在build-profile.json5 中添加如下这个是项目的，不是模块的，模块的加也没问题
在app下
在products下
在buildOption下

"app":{
	"products":[
		"buildOption":{
          "externalNativeOptions": {

            "path": "./src/main/cpp/CMakeLists.txt",
            "abiFilters": [
              "arm64-v8a",
              "x86_64"
            ]
          },
          ...

5.模块下的
添加引用so的依赖

 "libentry.so": "file:./src/main/cpp/types/libentry"

6.好了可以使用了

import testNapi from 'libentry.so';
...
  build() {
    RelativeContainer() {
      Text(this.message)
		.onClick(() => {
          let str:string = JSON.stringify(testNapi.add(1,1))
          console.log('11111:'+str)
                })

7.咦 发现报错了，，说什么cmake …
The path of the cmake script in externaNative0ptions is empty. use the default path ./src/main/cpp/cMakelists.txt
The configqured cmake script in externalNativeptions/path does not exist.
If there are no issues in this file, perhaps you have used 'overrides’ in ‘hvigorfile.ts’, please check it.

没错，就是CMakeLists缺少
咱先复制进来
里面的东西呢
按照我下面的来

# the minimum version of CMake.
cmake_minimum_required(VERSION 3.5.0)
project(Libentry)
#设C++标准
Set(CMAKE_CXX_STANDARD 17)
#set(NATIVERENDER_ROOT_PATH ${CMAKE_CURRENT_SOURCE_DIR})
# 1.定义SO库的根目录(指向entry/libs)
Set(SO_LIB_ROOT ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs)

#2. 根据目录架构自动选择对应的目录
if(${OHOS_ARCH} STREQUAL "armeabi-v7a")
    set(SO_ARCH_DIR "armeabi-v7a")
elseif(${OHOS_ARCH} STREQUAL "arm64-v8a")
    set(SO_ARCH_DIR "arm64-v8a")
eLseif(${OHOS_ARCH} STREQUAL "x86_64")
    set(SO_ARCH_DIR "x86_64")
else()
message(FATAL_ERROR "Unsupported architecture: ${OHOS_ARCH}")
endif()

#3、拼接当前架构的SO库目录
Set(SO_LIB_DIR ${SO_LIB_ROOT}/${SO_ARCH_DIR})

# 4.声明外部预编译库(关键修复)
add_library(libentry SHARED IMPORTED)

# 指定外部库的实际路径
set_target_properties(libentry PROPERTIES
    IMPORTED_LOCATION "${SO_LIB_DIR}/${OHOS_ARCH}/libentry.so"
)
#5.添加SO库搜索路径
link_directories(${SO_LIB_DIR})

#6.引入头文件目录
include_directories(${CMAKE_CURRENT_SOURCE_DIR})

对应的so库的名字自行修改
好了，大家有什么疑问，可以一起讨论，我的三方库引用到这了
