HarmonyOS C++ image receiver的内容缺少符号，报错？

Question

cmakelist里加了这2个库的依赖，libohimage.so，libimage\_receiver.so。报错信息如下：

ld.lld: error: undefined symbol: OH_ImageReceiverOptions_Create
>>> referenced by LavaHarmonyVideoDeviceTni.cpp:540 (/Users/xxx/Workspace/lava-stable/src/ohos/LavaHarmonyVideoDeviceTni.cpp:540)

在进行应用开发之前，需要打开native工程的src/main/cpp/CMakeLists.txt，在target\_link\_libraries依赖中添libohimage.so，libimage\_receiver.so，libnative\_image.so 以及日志依赖libhilog\_ndk.z.so。
