make build in aarch64 centos8 about tf-encrypted-master

Hello,I meet a problem:make build in aarch64 centos8 about tf-encrypted-master. see:

[root@centos8 tf-encrypted-master]# export CPATH=/root/0526/tf-encrypted/tensorflow-1.15.2
[root@centos8 tf-encrypted-master]# make build

Can you help me?

@zicofish .I have found the problem: The TensorFlow and third_party folders are stored in the /usr/local/lib/python3.6/site-packages/tensorflow_core directory by default during TensorFlow installation by PIP. Therefore, the two folders are not found in the /usr/local/lib64/python3.6/site-packages/tensorflow_core/include directory. The make build problem has been solved:

[root@centos8 tf-encrypted-master]# make build
mkdir -p tf_encrypted/operations/secure_random
g++ -std=c++11 -shared operations/secure_random/secure_random.cc -o tf_encrypted/operations/secure_random/secure_random_module_tf_1.15.2.so \
        -fPIC -I/usr/local/lib64/python3.6/site-packages/tensorflow_core/include -D_GLIBCXX_USE_CXX11_ABI=1  -O2 -I/root/0526/tf-encrypted/tf-encrypted-master/build/include -L/root/0526/tf-encrypted/tf-encrypted-master/build/lib -lsodium

Thank you for the reminder and help in resolving my confusion.
