#   - fabric-ca-client - builds the fabric-ca-client executable
#   - all-tests - runs unit and integration tests
#   - int-tests - runs the go-test based integration tests
#   - unit-tests - runs the go-test based unit tests
#   - checks - runs all check conditions (license, format, imports, lint and vet)
#   - native - ensures all native binaries are available
#   - docker[-clean] - builds/cleans the fabric-ca docker image
#   - docker-fvt[-clean] - builds/cleans the fabric-ca functional verification testing image
