Subject: [PATCH v4 8/8] build: meson changes to build on windows
Date: Fri, 22 Mar 2019 15:55:05 -0700	[thread overview]
Message-ID: <20190322225505.13988-9-anand.rawat@intel.com> (raw)
In-Reply-To: <20190322225505.13988-1-anand.rawat@intel.com>

Added meson workarounds to build helloworld on windows.
Windows currently only supports kvargs and eal libraries.
This change restricts the build flow to supported libraries
only.
