[Luis Ibanez]

Hi Ekta,

Thanks for the additional information.

It seems that you are building the examples by running CMake
in the Examples directory.   Is that right ?

The examples are intended to be build as part of the
full toolkit, just by turning EXAMPLES On in CMake,
and then building the project with your compiler.

If you want to extract examples out of the toolkit,
you must write CMakeLists.txt files for the examples
that you use.

Since you are new to the toolkit, I would strongly
suggest you to read the Tutorials:

     http://www.itk.org/HTML/Tutorials.htm

in particular:

"Getting Started I"
http://www.itk.org/CourseWare/Training/GettingStartedI-WebPage/index.htm

as well as to read initial Chapters of the
ITK Software Guide:


    http://www.itk.org/ItkSoftwareGuide.pdf

These documents will introduce you progressively to
the use of the toolkit.


    Regards,


       Luis
