Subject: [dpdk-dev] [PATCH 19.08 6/6] examples/vhost_crypto: support building from pkg-config info
Date: Fri,  3 May 2019 14:35:37 +0100	[thread overview]
Message-ID: <20190503133537.58712-7-bruce.richardson@intel.com> (raw)
Message-ID: <20190503133537.69eySnjiXM5IqZe_nOehcQW3f7qfsa3aM4Ld87FaNR0@z> (raw)
In-Reply-To: <20190503133537.58712-1-bruce.richardson@intel.com>

The vhost_crypto example app did not check for a libdpdk pkg-config file
and attempt to build using that. Add support for that method of compile to
align the app with the other examples.
