CMake: Add missing iconv dependency

FreeBSD has two iconv systems: It ships an iconv.h itself,
and symbols for that in the libc. But there's also the port
of GNU libiconv, which unfortunately for us, Doxygen depends
on.

This changes things to prefer a separate libiconv library
over the system one; that is, the port on FreeBSD.
