If it helps, I made a PPA:

  https://launchpad.net/~dcthomp/+archive/ubuntu/smtk/+packages

for building some software (SMTK) on Travis that requires CMake 3.x. If you are going to install a modern VTK (instead of whatever version LTS comes with), then it seems reasonable to depend on a modern CMake.
