Why ? (I believe you can build DICOMParser and most utilities stand alone as
well)

MetaIO/CMakeLists.txt would simply check if the few vars are not already
defined and if so assign then.

if (NOT METAIO_NAMESPACE)
  set( METAIO_NAMESPACE "..." )
endif(NOT METAIO_NAMESPACE)


This way, its can be used as a part of packages other than ITK and VTK and
being built standalone as well, right ?

Thanks
