It's a really bad idea to imply that citation is a legal requirement in the
license. Such a requirement makes your code non free/open-source software.
The best approach is to simply make a polite request, but be explicit that
it is not a legal requirement. In practice, people will happily comply
with such a request in my experience. e.g. this is what we say for FFTW:
In addition, we kindly ask you to acknowledge FFTW and its authors
in any program or publication in which you use FFTW. (You are not *required* to
do so; it is up to your common sense to decide whether you want to comply
with this request or not.) For general publications, we suggest
referencing: Matteo Frigo and Steven G. Johnson, “The design and
implementation of FFTW3,” *Proc. IEEE* *93* (2), 216–231 (2005).
