Undefined references related to mbedtls

[jordibinefa]

Mr. Stefan Profanter,

I really appreciate your sharing. Thank you very much.

I am trying to compile your code and, at the end, there are some undefined references related to mbedtls. I guess there are some *_mbedtls.h files not defined somewhere. Or maybe there is something obvious that I am overlooking.

This is part of terminal output:

Thank you very much for reading this personal issue.
