[Insight-users] CMake warning(dev) in Cmakelists.txt

[Stuart Golodetz]

It means that when the person who wrote the CMakeLists.txt file for the 
project was doing so, they didn't put a line like this at the top:

cmake_minimum_required(VERSION 2.6)

The purpose of this is to prevent old versions of CMake being used with 
projects they can't handle. See the following:

http://www.cmake.org/cmake/help/cmake2.6docs.html#command:cmake_minimum_required

I'd guess cmake_minimum_required may not have been available/required 
when the CMakeLists.txt files for the itk examples were being written - 
so it's just a harmless case of files being outdated by ever-advancing 
tools (i.e. not the fault of the people who wrote the files).

Bottom line: ignore the warnings :)

Regards,
Stu
