Yes, it really is a better developer experience, and you probably
didn't notice that ninja automatically does stuff like 'make -O' (and
it actually fully works) and tracks changes to the build commands
(like kbuild).. For those reading my system can go from a clean git
checkout to a full build of all 15 libraries in 3.5s.

The install is done in the usual way:

(make or ninja) install

DESTDIR environment var works as usual for packagers.

That does exactly the same as 'make install' did for auto*, which is,
IMHO, somewhat useless since it goes into /usr/local.

The full install to / is still a small TODO, it is part and parcel
with doing the packaging, in my mind.

But the basic starting point is:

cmake .. -DCMAKE_SKIP_RPATH=ON  -DCMAKE_INSTALL_PREFIX=/usr

But a bit more work is needed to make SYSCONFDIR work right..

I also want to make a patch to 'run in place' (eg with
LD_LIBRARY_PATH), which makes sense now that the providers build
along-side libverbs.

It isn't too hard but lets get agreement on this direction at all
first...
