Subject: [PATCH 5/6] libtracefs: Use pkg-config to find libtraceevent
Date: Tue, 08 Dec 2020 16:54:09 -0500	[thread overview]
Message-ID: <20201208215504.983661503@goodmis.org> (raw)
In-Reply-To: 20201208215404.135186972@goodmis.org

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

As libtracefs is dependent on libtraceevent, use the proper pkg-config
method to find where libtraceevent is installed.
