From 3b6502fd808f7a9e3ece1be4287dcf0ac8028b15 Mon Sep 17 00:00:00 2001 From: Jonathan Rajotte Date: Tue, 1 Dec 2015 15:19:01 -0500 Subject: [PATCH] Build: fallback to AC_CHECK_LIBS when looking for popt and uuid MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Not all distro ship .pc so fallback to basic libs searching if necessary.
