Imagine this paragraph is also here, and the patch having the
corresponding hunk. I missed the part of Daniel's reply that pointed
it out:
Array options require a bump of required meson version to 0.44. Debian
stable has meson 0.37 which is already too old, stable-backports has
0.45, CI uses 0.45. Mesa's meson requirement is 0.44.1, for a
perspective.
