4.  多平台配置
    
    > 新增build-profile.json5下abiFilters，支持多平台  
    >     "externalNativeOptions": {  
    >       "path": "./src/main/cpp/CMakeLists.txt",  
    >       "arguments": "",  
    >       "cppFlags": "",  
    >         
    >       "abiFilters": \[  
    >         "x86\_64",  
    >         "arm64-v8a"  
    >       \]  
    >     }
    
5.  点击锤子🔨make module生成，右上角圆点切换debug|release。输出文件在build\\default\\outputs\\default\\\*.hap，解压有ABI对应的.so文件。
6.  ts或其它库调用使用时，需在src同级目录下新建libs文件夹，拷贝abiFilters所有文件夹到libs下。

###### .so cmake配置

```cpp
cmake_minimum_required(VERSION 3.5.0)
project(NativeFileAccess)

set(NATIVERENDER_ROOT_PATH ${CMAKE_CURRENT_SOURCE_DIR})

if(DEFINED PACKAGE_FIND_FILE)
    include(${PACKAGE_FIND_FILE})
endif()

include_directories(${NATIVERENDER_ROOT_PATH}
                    ${NATIVERENDER_ROOT_PATH}/include)
link_directories(${NATIVERENDER_ROOT_PATH}/../../../libs/${OHOS_ARCH})

add_library(file_access SHARED FileAccessMethods.cpp)

if (CMAKE_BUILD_TYPE STREQUAL "Debug")
    set_property(TARGET file_access PROPERTY IMPORTED_LOCATION ${NATIVERENDER_ROOT_PATH}/libs/${OHOS_ARCH}/libfreetyped.so)
else()
    set_property(TARGET file_access PROPERTY IMPORTED_LOCATION ${NATIVERENDER_ROOT_PATH}/libs/${OHOS_ARCH}/libfreetype.so)
endif ()

set_property(TARGET file_access PROPERTY IMPORTED_LOCATION ${NATIVERENDER_ROOT_PATH}/libs/${OHOS_ARCH}/libc++_shared.so)
target_link_libraries(file_access PUBLIC libace_napi.z.so libhilog_ndk.z.so librawfile.z.so libc++_shared.so)
target_link_libraries(file_access PUBLIC debug libfreetyped.so optimized libfreetype.so)
