Regression: Weston build fails (incorrect include order)

Build setup:

• Ubuntu 18.04 (gcc 7.4)
• Meson v0.49 (from Ubuntu 19.04 due to #293 (closed))
• Git head of Weston and it's main deps (Mesa etc)

Weston build broke within couple of last days:

$ meson -Dimage-jpeg=false -Dimage-webp=false -Dsimple-dmabuf-drm=auto -Dxwayland-path=/opt/install/bin/Xwayland -Dpipewire=false -Dbackend-drm-screencast-vaapi=false -Dbackend-rdp=false -Dremoting=false --buildtype=debugoptimized ../source/weston

Attached patch fixes it: 0001-Fix-include-order-to-unbreak-build.patch

I think you need to increase you build testing.
