From a81df1b68b656f2487f556240baf2af83e60ec6c Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Wed, 19 Aug 2020 08:44:56 -0400 Subject: libqemuutil, qapi, trace: convert to meson This shows how to do some "computations" in meson.build using its array and dictionary data structures, and also a basic usage of the sourceset module for conditional compilation. Notice the new "if have_system" part of util/meson.build, which fixes a bug in the old build system was buggy: util/dbus.c was built even for non-softmmu builds, but the dependency on -lgio was lost when the linking was done through libqemuutil.a. Because all of its users required gio otherwise, the bug was hidden. Meson instead propagates libqemuutil's dependencies down to its users, and shows the problem.
