make in openenclave_test/ on SGX-machine fails with unresolved references during link phase.

[gapisback]

After fixing Makefiles to handle the reference(s) to certprotos/certifier.proto [ changes arising from fixes to address issue #116 ], the following simple make command fails on SGX-machine:

sgx-server:[60] $ pwd
/home/sgx/agurajada/certifier-framework-for-confidential-computing/openenclave_test

make

The fix to access certifier_service/certprotos/certifier.proto is working fine:

Processing /home/sgx/openenclave-bin/share/pkgconfig/../../include/openenclave/edl/sgx/switchless.edl.
Success.
../protobufs-bin/bin/protoc --cpp_out=. --proto_path=../../certifier_service/certprotos ../../certifier_service/certprotos/certifier.proto

Later we fail at link phase:

NOTE: Similarly: $ make in openenclave_test/enclave also fails.

This whole build in this openenclave_test/ needs to be re-examined.

Not important to resolve before the summit.
