Hi Lydia,

Thanks for sending the full list of error messages
that was very helpful.

I just followed step by step the process that you
described and could reproduce the problem that you
reported. It seems that all the problem is related
with paths and libraries that are missing  in your
CMakeList.txt file.

For example, the first error in you compilation can
be solved by adding:

${ITK_SOURCE_DIR}/Auxiliary/MetaImage/IView

to the INCLUDE_DIRECTORIES() block in CMakeLists.txt

I made a set of changes along these lines on the
CMakeLists.txt file from the GaussianFilter and
got it to compile, link and run.

Attached is the modified CMakeLists.txt file with
which you can make the GaussianFilter example work
from outside ITK (as an external project).

Note that it is specifying a lot of directories for
the INCLUDE paths, the LINK paths and is also listing
all the libraries required for linking, in particular
I had to add:

   ITKNumerics
   VXLNumerics

What happens with the examples inside the ITK.dsw is
that they inherit some of these paths from the global
ITK settings. When the project is made external you
have to provide CMake with all the paths (include/link)
and libraries that your code requires to build.

Please let us know if this CMakeLists.txt file works
for you and if the same approach solve the first
problem you were having with IO.


   Thanks

     Luis
