From Peter Harris via https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=4820 :

Mesa moved its API description file again.

Also, while I'm here, I noticed that they stopped using signed tags, so add
--tags to "git describe" for a better description of the mesa version used to
build the X11 dissector.
