fatal error: sgx_spinlock.h: No such file or directory

[AiDaiP]

I set up SecretNetwork according to README, but build failed.
I think this may be related to sgx not being installed successfully.

  command did not execute successfully: "make" "INCDIR=/home/ubuntu22/blockchain/SecretNetwork/third_party/incubator-teaclave-sgx-sdk/sgx_unwind/../sgx_unwind/libunwind" "-j64"
  expected success, got: exit status: 2
