Subject: configure: error out when building X11 Vulkan without DRI3
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=05043e0e8e0bd5e3019f480557d452b4c165f8f2;p=mesa.git

configure: error out when building X11 Vulkan without DRI3

Vulkan supports only DRI3 enabled X11 platforms. Make it obvious,
should one consider building without it.
