From b352cee6f8113e63864ac644502ace3bd75bfae1 Mon Sep 17 00:00:00 2001 From: Marius Vlad Date: Wed, 12 Feb 2020 13:00:36 +0200 Subject: meson.build: Build X11 backend optionally libweston6 built and installed the x11 backend unconditionally, but this is no longer the case with newer version of weston. Also, poky-agl configuration specifically removes any distro features that contain x11. Users wanting to test the compositor under a x11 backend need to compile their own libweston version this shouldn't be a problem. Unfortunatelly, meson does not have a easy way to determine if a header is installed or not so after glancing over the documentation we need to use the compilers' 'has_header' function to determine if the x11 header was installed or not by the weston recipe. This makes sure that if we're building out-of-tree it finds the proper header as well.
