How to build in android platform?

int main() {
std::string tokenizer_json_path = "../tokenizer.json", path;
std::unique_ptrtokenizers::Tokenizer m_tokenizer;

path = LoadBytesFromFile(tokenizer_json_path);
cout<<"load file success !"<<endl;

m_tokenizer = tokenizers::Tokenizer::FromBlobJSON(path);

Here is my CMakeLists.txt info:
{

cmake_minimum_required(VERSION 3.18)

project(target)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED True)

aux_source_directory(. SRC_FILES)

link_directories(libs)

include_directories(include)

add_executable(target ${SRC_FILES})
target_link_libraries(target
${PROJECT_SOURCE_DIR}/libs/libsentencepiece.a
${PROJECT_SOURCE_DIR}/libs/libtokenizers_c.a
${PROJECT_SOURCE_DIR}/libs/libtokenizers_cpp.a
)

}

When I test, met the following issues:

Start with the reported CMakeLists.txt and its target_link_libraries entries, then inspect how the bundled libtokenizers_cpp.a and related libraries are built and linked for Android. Use the listed undefined tokenizers_* symbols to trace the missing dependency; done means the Android build instructions and required link inputs are clear and the sample target links successfully.
