Cannot locate shared object to plugin to protocol buffers generator.
Thought the file would be located at #{GENERATOR_FILE_PATH}
If you are running on Windows you should compile protocol buffer
definitions on another VM and then use those definitions locally.
Only the compiler is restricted by this. The definitions should work without issue.
