At our institute we have a script that checks-out the appropriate CVS
modules from our server (for example the ITK module that we have
comitted to our CVS server) and create a visual studio solution. This is
the main reason for not using CMake. Technically it would be possible to
integrate CMake in our environment, but for now that seems like a lot of
work.

Could you please elaborate on the use of itksys? When should I use this
and when shouldn't I?

best,
Jeroen

P.S.:
I managed to trigger an internal compiler error on line 4 here:

#include <itkImageSpatialObject.h>

template < typename CoordRepType, int Dim >
double f ( const itk::Point < CoordRepType, Dim > &_dummy )
{
  return 0.0;
}

int main ( int, char ** )
{
  return 0;
}

It wouldn't be fair to blame ITK for this, of course. Let's just say
that today is not a good day for me, compiling wise.
