From 14efd8d3b5fee7027f0ee072aea6620e0655774f Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Wed, 20 Apr 2022 17:33:47 +0200 Subject: meson, configure: move Xen detection to meson This is quite a complicated check. I moved all the test programs to a single file in scripts/, picking the right program with #if and a -D flag in meson.build's cc.links() invocation.
