Subject: [PATCH 1/6] lib: allow recursive disabling of libs in build
Date: Thu, 13 Jan 2022 17:39:13 +0000	[thread overview]
Message-ID: <20220113173918.2700651-2-bruce.richardson@intel.com> (raw)
In-Reply-To: <20220113173918.2700651-1-bruce.richardson@intel.com>

Align the code in lib/meson.build with that in drivers/meson.build to
enable recursive disabling of libraries, i.e. if library b depends on
library a, disable library b if a is disabled (either explicitly or
implicitly). This allows libraries to be optional even if other DPDK
libs depend on them, something that was not previously possible.
