Description

Looks like the PROTOC_IS_COMPATIBLE check fails when Protobuf library is built from source. This happens because the check if performed during the cmake phase, and the protobuf library needed for this test is build from source only during the make phase, so the check fails with "ld: cannot find -lprotobuf" because it was not built yet. We should probably restrict this test to run only in cases when Protobuf library is already present and not being built from source.
