Jim Broadus e7364263b2 build: Move minimum cmake version to 3.0.0
Compatibility with versions prior to 2.8.12 is being deprecated,
resulting in build warning messages. The minimum for the official
supported distros is 3.7.2 (Stretch), so the version could be moved
forward when newer features are required.
