Subject: v4l2src: link against -lrt for clock_gettime()
X-Git-Tag: 1.19.3~509^2~6329
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=527c21853352ff3c9c26edf508cc2395410c7817;p=platform%2Fupstream%2Fgstreamer.git

v4l2src: link against -lrt for clock_gettime()

Need to explicitly link against -lrt for clock_gettime(), which
we don't get in the libs any more, because core moved the
gmodule-no-export-2.0 bit into Requires.Private.

Not required for newer glibc, but for older ones, so check for that.
