[Insight-users] read image error in Examples

[Luis Ibanez]

Hi Xi,

Yes, adding the line

> cmake_minimum_required(VERSION 2.8)

Is necessary when you move the examples out of the ITK
source tree (which is the right thing to do in your case).

When the examples are inside the ITK source tree, this line is not
needed and that's the reason why you don't see this line in any of
the CMakeLists.txt files of the examples.


The lines

> FIND_PACKAGE(ITK REQUIRED)
> INCLUDE(${ITK_USE_FILE})

are also required (as you already discovered).


You will save a lot of time if you actually read the Tutorials:

         http://www.itk.org/ITK/help/tutorials.html

in particular, you must read:

http://www.itk.org/CourseWare/Training/GettingStarted-I.pdf

All these details about the CMakeLists.txt file are
described there.

You will find this instructions in the ITK Software Guide
as well.

   Regards,


         Luis
