CMake upstream here. We recommend always using the very latest patch 
version of CMake, since it is backwards compatible and can 
(theoretically, bugs notwithstanding) build CMake projects written for 
any earlier version of CMake. You are correct that upgrading CMake is 
generally easy, though it admittedly may not be feasible if you insist 
on sticking with the version provided by the distro (though we do 
provide Ubuntu .deb builds of the latest version.)
