commit 080e614bd975aa3784a463a8a0b50885bc65c726
Author: Raphael Kubo da Costa <rakuco@FreeBSD.org>
Date:   Fri Mar 25 00:21:04 2016 +0100

    Link against ${CMAKE_DL_LIBS} instead of libdl.

    -dl only exists on Linux, so linking fails on other OSes like FreeBSD.
    Use the portable CMAKE_DL_LIBS variable instead.
