It's not Ubuntu 16.04 that matters but vivid+overlay since we're still building against it, we have 3.0.2 there (we could backport it if really needed)

Please set https://wiki.ubuntu.com/Process/Merges/Checklists/Unity8 as description and a proper commit message.

Update the minimum cmake version to 3.0

The build depends on the CMAKE_AUTORCC feature which was first introduced in
CMake 3.0. Given that Ubuntu 16.04 ships with CMake 3.5, the minimum version
could be raised yet higher to take advantage of more features such as
transitive usage requirements.
