For the default, how about we default to OFF to start while turning it
ON for the dashboards. When work completes, we can wait for X weeks then
default it to ON.

I think adding a PPA is fine here. We might need to consider those who
don't have root and can't use PPAs as well and provide from-source
instructions.

Fedora has 2.8.12.2 in F20 and F19 and below are EOL anyways. I have a
copr for CMake master here[1] I update sporadically and can spin up
another for 3.x if wanted. I think I can build against EPEL5 as well,
but I'd have to double check (EPEL6 is definitely possible).
