[Mesa-dev] [PATCH kmscube] meson build support (v3)

[Rob Clark]

Figured I should figure out what this meson stuff is all about.  After a
bit of hunting around to find examples to look at (and interruptions) it
took maybe ~1hr to convert (for someone who never looked at meson
before).  The build speed is definitely faster even after Emil's auto-
tools improvements:

meson:
	real	0m1.310s
	user	0m2.069s
	sys	0m0.459s

autotools:
	real	0m4.489s
	user	0m3.754s
	sys	0m0.731s

(with gst / video-cube enabled, fresh build in either case so it is
including the time spent compiling .c files in both cases)

Updated with feedback from various folks.. also tried to make the gst
support configurable.. which seems to work, but not sure if there is
a more canonical way to do the true/false/auto thing.
