examples/vdpa: support build with pkg-config
The vdpa 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. Signed-off-by: Bruce Richardson <bruce.richardson@intel.com> Acked-by: Luca Boccassi <bluca@debian.org>
