移植openharmony添加组件ace编译报错文件解决
首先在我们的vendor/xingyun/t113_nand/config.json文件中添加组件ace后，如下图所示组件
{ "subsystem": "ace", "components": [ { "component": "ace_engine_lite", "features":[ "" ] } ] }一进行编译发现会报错如下，但是我们芯片根本就不是海思啊。所以需要追踪下是哪里引用了这个文件夹路径参与编译的。

打开foundation/ace/ace_engine_lite/frameworks/BUILD.gn文件，搜索看有没有foundation/multimedia/camera_lite/frameworks相关字段，可以看到是包含了的。
针对以上情况，有两种解决方案给出，如果是使用摄像头产品，肯定是修改对应引用的文件去进行修改，这样也稳妥，不会出现对应奇怪的问题，比如我这边是直接暴力修改

目前我是这样解决的

文件device/xingyunelec/hardware/media/BUILD.gn内容如下，对接上文两处修改的文件。
import("//build/lite/config/component/lite_component.gni")group("hardware_media_sdk") { deps = [ "audio:lib_audio", "codec:lib_codec", "format:lib_format", "common:lib_common", "camera:lib_camera", "videodisplay:lib_videodisplay", ]}这里放出一个子目录具体实现。后面依此类推即可。
BUILD.gn内容如下
import("//build/lite/config/component/lite_component.gni")copy("audio_hw") { sources = [ "//device/${device_company}/hardware/media/audio/libaudio_hw.so" ] outputs = [ "$root_out_dir/libaudio_hw.so" ]}copy("audio_input_port") { sources = [ "//device/${device_company}/hardware/media/audio/libaudio_input_port.so" ] outputs = [ "$root_out_dir/libaudio_input_port.so" ]}copy("audio_output_port") { sources = [ "//device/${device_company}/hardware/media/audio/libaudio_output_port.so" ] outputs = [ "$root_out_dir/libaudio_output_port.so" ]}group("lib_audio") { deps = [ ":audio_hw", ":audio_input_port", ":audio_output_port", ] }修改完成后，执行编译，可以成功编译，后期就可以我们自己添加自己的文件进行编译即可，不会和海思目录文件强绑定了。
