Help: xref variable that cmake_minimum_required() sets

Browse Source 
The CMAKE_MINIMUM_REQUIRED_VERSION has long been set by

the variable isn't very discoverable without it being mentioned in
the command's docs as well.

higher. It should be specified so CMake versions 2.4 and lower fail
with an error instead of just a warning.
