Dear Kenton and Aron,

thank you very much for your prompt answers.

With Kenton's suggestion, we were able to have our custom
OVERLOOK_EXPORT macro in the generated .pb files.

By using Aron's idea we then managed to force inclusion of our
exports.h file.

Thank you all again.
Kind regards,

Carlo
