When adding google/boringssl to the project in Android, an undefined reference to function error occurs

Question

I'm trying to use google/boringssl through NDK on Android.

I added the code in the are directory.

- include/openssl
- include/openssl/pki
- include/openssl/experimental
- ssl/
- crypto/
- third_party/fiat

Now we have add_library(...) all .c files and .c++ files to CMakeLists.txt.

I compiled the project thinking everything was done, but I get an error.

openssl/crypto/fipsmodule/sha/sha1.c:421: error: undefined reference to 'sha1_block_data_order_neon'
openssl/crypto/fipsmodule/sha/sha1.c:427: error: undefined reference to 'sha1_block_data_order_nohw'
openssl/crypto/cipher_extra/e_chacha20poly1305.c:173: error: undefined reference to 'chacha20_poly1305_seal'
openssl/crypto/cipher_extra/e_chacha20poly1305.c:256: error: undefined reference to 'chacha20_poly1305_open'
openssl/crypto/fipsmodule/ec/p256-nistz.c:247: undefined reference to `ecp_nistz256_point_add'
...

As shown above, there are many functions that are declared but not implemented. Is there a specific way to use boringssl in the Android environment??
