Subject: [PATCH 1/2] keyutils: Add pkg-config file for keyutils library
Date: Fri, 12 Oct 2018 18:08:07 +0000	[thread overview]
Message-ID: <153936768778.53805.17270502000080117870.stgit@djiang5-desk3.ch.intel.com> (raw)

This is needed so that other projects can add a dependency on libkeyutils
via PKG_CHECK_MODULES([KEYUTILS], [keyutils]).  This enabling makes 'make
install' do the right thing, and of course individual distros will need to
add enabling to their associated packages (rpm, deb, etc.) so the package
manager installs do the right thing.
