make -f oe_certifier.mak in analytics_example/enclave/ dir fails with: No rule to make target 'oe_certifier.cc

[gapisback]

While attempting to clean-up references to certifier.proto [ in the wake of fixes for issue #116 ], attempted to run make in the named sub-dir. This fails as follows (tried on Nimbus-VM):

cc-sdb-vm:[328] $ pwd
/home/agurajada/Code/certifier-framework-for-confidential-computing/sample_apps/analytics_example/enclave
cc-sdb-vm:[329] $ make -f oe_certifier.mak
make: *** No rule to make target 'oe_certifier.cc', needed by 'oe_certifier.o'.  Stop.

Even after resolving the Makefile logic, this fails finally as follows:

Don't need this to be resolved before the summit.

We may deprecate this example. We should if we don't fix it and remove it from the repository (or move it to "deprecated.")
