I know you've already solved your immediate problem, but I think this 
over-dependence on libsndfile should be fixed in 3.10.5.0 after this PR:
https://github.com/gnuradio/gnuradio/pull/6178

OOT modules that don't themselves use libsndfile (probably all of them) 
will no longer need to install it to build against GR 3.10.5.0, and thus 
there would be no need to have Debian packages pull in libsndfile1-dev 
as a dependency.

See also the bug report for reference:

Cheers,
