MOD: Modifies cmake include for protobuf

- sets the protoc path in CMakeLists.txt file so it can also be used in top level projects
 - sets the proto source file path so it can be used in top level projects
 - uses cmake variable PROTO_SRC_PATH defined in CMakeLists for the custom command in the protobuf.cmake file
