Since commit
a94553231470 ("meson: Convert `v4l2` into a feature option")

the 'v4l2' option is not a boolean anymore but instead a feature
which should be controlled with -Dv4l2=enabled or -Dv4l2=disabled

Your build directory has been configured before that commit went in,
when 'v4l2' was a boolean. Either try to reconfigure the build dir
(meson --reconfigure) or delete your build dir and create a new one.
