Alright !

Hum...those file were automatically generated by cmake. I'll have to
check what's wrong. Thanks for report.

You did exactly what was expected. Have you ever done any major Win32
devplt ? If not there is two ways to use dll on Win32 system:
- put them at the exact location of the executable you are trying to run
- if you have two (or more) executable at different location, it
becomes cumbersome, in which case, it is better to modify the PATH
environment of your win32 user (panel/settings/env variables/PATH)

What compiler did you use to compile VTK ? I am pretty sure this will
go away once you compile both GDCM and VTK with the same compiler. But
as a side note I am also experiencing some issue with gdcmviewer, so
consider using gdcmviewer2 for now (binaries will be uploaded
shortly).

GDCM has never been part of VTK and I doubt it will ever be merged back in IMHO.
There is a chance that gdcm2 once it mature a little more might
replace the old gdcm1 shipped currently with ITK, but this might take
a while !

Error logs are the best you could ever do :)

What kind of compiler are you using ? Are you using VS6 ?

Fixed, sorry before the release I forgot I had some local change on my
win32 machine too (most of the time I am doing on my linux box).

Fixed. Thanks.

Hum this one I am not sure. But please try again the complete build. Thanks.

that was my mistake (local change not commited).
