From 0572d6cd29d6434de166ce67a29fc8ff64777218 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Mon, 25 Jan 2021 11:09:58 +0000 Subject: trace: add meson custom_target() depend_files for tracetool Re-generate tracetool output when the tracetool source code changes. Use the same approach as qapi_gen_depends and introduce a tracetool_depends files list so meson is aware of the dependencies.
