Subject: [PATCH 1/3] libtraceevent: Add a way to uninstall
Date: Tue, 15 Dec 2020 23:36:38 -0500 [thread overview]
Message-ID: <20201216043716.818873731@goodmis.org> (raw)
In-Reply-To: 20201216043637.453360298@goodmis.org
From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>
Add an uninstall target. The way this works is to create a temp directory,
build and install into it. The examine the files in that directory, to know
what files need to be removed. The DESTDIR and prefix need to be the same as
how the install happened.
