how to integrate sentencepiece, protobuf into existing android project correctly

Question

I am trying to integrate pytorch model to process language. This is why I need the sentencepiece to tokenize the sentence chunks. But I am unable to do that correctly.

I did not find any robust documentation of integrating sentencepiece into android app. The way I tried is.

• I copied the source code(https://github.com/google/sentencepiece) to android app like the we do CPP files. now the problem is , there is throwing some error with protobuf.

  CMake Error at C:/Users/Reve/AppData/Local/Android/Sdk/cmake/3.18.1/share/cmake-3.18/Modules/FindPackageHandleStandardArgs.cmake:165 (message): Could NOT find Protobuf (missing: Protobuf_INCLUDE_DIR) Call Stack (most recent call first): C:/Users/Reve/AppData/Local/Android/Sdk/cmake/3.18.1/share/cmake-3.18/Modules/FindPackageHandleStandardArgs.cmake:458 (_FPHSA_FAILURE_MESSAGE) C:/Users/Reve/AppData/Local/Android/Sdk/cmake/3.18.1/share/cmake-3.18/Modules/FindProtobuf.cmake:626 (FIND_PACKAGE_HANDLE_STANDARD_ARGS) CMakeLists.txt:106 (find_package)

Now can anyone please tell me how to solve this error or can anyone give me the guidance to integrate the sentencepiece into the android apps correctly...
