that is a little more difficult to understand than usual, why don't we just use the bb.utils.contains?

${@bb.utils.contains('DISTRO_FEATURES', 'x11 wayland', '${PACKAGECONFIG_VULKAN}', '', d)

It seems to me that this would work.

Or even the following, dropping the PACKAGECONFIG_VULKAN but then it loses some readability again.

${@bb.utils.contains('DISTRO_FEATURES', 'x11 wayland', '${@bb.utils.filter('DISTRO_FEATURES', 'vulkan', d)}', '', d)

I don't use bb.utils.contains because we need any of x11, wayland, not all of them.

I changed to use contains_any to make things more simple in V3

Thanks
