From e0130788576fb85039f5c491b82575a0190f5d4b Mon Sep 17 00:00:00 2001 From: David Hunt Date: Wed, 17 Oct 2018 14:05:33 +0100 Subject: [PATCH] examples/power: support meson/ninja build Add meson.build in vm_power_manager and the guest_cli subdirectory. Building can be achieved by going to the build directory, and using meson configure -Dexamples=vm_power_manager,vm_power_manager/guest_cli Then, when ninja is invoked, it will build dpdk-vm_power_manger and dpdk-guest_cli Work still needs to be done on the meson build system to handles the case where the target list of example apps is defined as 'all'. That will come in a future patch.
