libiconv not found, so character conversion unsupported

[Sjors Gielen]

DCMTK 3.6.1 has an option to use libiconv to support character conversion. It looks like this option is explicitly turned on in the rules file:

    -DDCMTK_WITH_ICONV:BOOL=ON \

However, since the Debian package does not depend on libiconv, it is not found during package build, which is ignored with only a warning:

    -- Could NOT find LIBICONV (missing: LIBICONV_LIBRARY)
    -- Warning: ICONV support will be disabled because libiconv was not found. Correct LIBICONV_LIBDIR and LIBICONV_INCLUDE_DIR and re-enable DCMTK_WITH_ICONV.

This causes the DCMTK tools to be unable to convert to UTF-8:

(from 'man dcmdump')
         +U8 --convert-to-utf8
                convert all element values that are affected
                by Specific Character Set (0008,0005) to UTF-8

                # requires support from the libiconv toolkit

$ dcmdump --convert-to-utf8
$dcmtk: dcmdump v3.6.1 2015-09-24 $

dcmdump: Dump DICOM file and data set
error: Unknown option --convert-to-utf8

And in the code, when .convertToUTF8() is called, a 'bad' OFCondition with text "No character encoding library available" is returned.

I would expect, especially considering WITH_ICONV is explicitly enabled, that iconv would be a necessary dependency for the package, and the resulting build is able to use iconv to convert incoming Dicoms to UTF-8.
