Subject: [PATCH 3/5] libtracefs: Add make uninstall
Date: Tue, 15 Dec 2020 23:38:55 -0500 [thread overview]
Message-ID: <20201216043921.621289635@goodmis.org> (raw)
In-Reply-To: 20201216043852.168982058@goodmis.org
From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>
Create the logic to remove the files that would normally be installed.
Note, this does take the DESTDIR and prefix variables into account. Where
the uninstall may only work for an install with the same variables.
