Yes, LGPL means that you cannot link in that proprietary code. You would 
have to do it as a separate app, which is called by a new (written by 
you) libfprint driver.

However, such code would not be accepted into libfprint (which is only 
interested in open code) and would be rejected by all major Linux 
distributions (due to the inclusion of proprietary software).
