Options for CMake commands

Question

The documentation for the cmake_minimum_required command says:

The FATAL_ERROR option is accepted but ignored by CMake 2.6 and higher. 
It should be specified so CMake versions 2.4 and lower fail with an error 
instead of just a warning.

But, it doesn't say what the valid options are for FATAL_ERROR - am I missing something blindingly obvious?

@KyleKanos Can you explain what the `FATAL_ERROR` option in `cmake_minimum_required` should be? A string? How do the arguments of `message` relate to those of `cmake_minimum_required`? — ChrisW, Jun 07 '13 at 17:23

There are no additional arguments required for FATAL_ERROR in the context of cmake_minimum_required.

You use it like this:

cmake_minimum_required(VERSION 2.8 FATAL_ERROR)

or

cmake_minimum_required(VERSION 2.8.11.1 FATAL_ERROR)

In the context of message, you do pass an additional argument:

message(FATAL_ERROR "My message...")
