The VXL Project

Hi all

I have added better DICOM support to vil via a subset of the DCMTK
libraries. I've put this subset in v3p/dcmtk. Whether this library is
compiled or not is based on the CMake option VXL_BUILD_DCMTK.  The
subset is about 4MB of C++ source, and so does take some time to
compile.  Since the set of DICOM users is probably small, I've set
this flag to "OFF" except for dashboard builds.

Two questions:

1. Should this variable be renamed to BUILD_DCMTK, or perhaps to
   BUILD_V3P_DCMTK, in keeping with other similar names? (BUILD_VGUI,
   BUILD_CORE_NUMERICS, for example)?

2. Should this variable be "ON" by default?

Note that even if DCMTK is not build, there will always be some DICOM
support from the routines written by the Manchester folks.

Thanks,
Amitha.
