[Insight-users] Problem with readers / writers in debug mode

[Iván Macía]

Hi Luis,

You were right, I was linking with release version of itkCommon because I
had it in the path but I wasn't receiving any warning / error. I find it a
problem that in the project CMake generates the debug and release version of
the common library have the same name (instead of calling them
itkCommond.lib and itkCommon.lib respectively for example). Of course it is
easy to change it manually.

Thank you very much for your help

Iván
