From 859aef026e51a4959d1ab535f0b7a00d63ed32ba Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 4 Aug 2020 18:14:26 +0200 Subject: [PATCH] meson: replace create-config with meson configure_file Move the create-config logic to meson.build; create a configuration_data object and let meson handle the quoting and output.
