Current Debian Stable (wheezy) has cmake 3.0.2.  Oldstable (jessie) has
2.8.4.

As for Ubuntu, according to https://wiki.ubuntu.com/LTS the oldest still
supported is 12.04 (Precise Pangolin) and they have 2.8.7:
http://packages.ubuntu.com/precise/cmake

For these systems, the CMake 2.8 functionality would be enough.  No need
to go back to 2.6.
