Re: Small patch to fix building librtlsdr on OpenBSD - osmocom-sdr

9 Nov 2019

Based on some cursory googling, it's _not_ needed for FreeBSD, but I haven't
tested. I'm not sure about the others.

A check for librt.so would be good; something like autoconf's AC_SEARCH_LIBS that
actually searches libs for clock_get time() would be best. I don't know what CMake has
to offer in that regard.

 is this applicable to the other BSDs too? 

 Ideally the rule would be "only link in rt if it's present", right?
