For the nox static libraries build, libtool in compile mode is invoked 239
times. 39,955 C header files are used – some of course a few hundred times or
such. This makes almost 170 C header files per C or C++ source code file. To
compile the SVG module, 200 C header files are used (it's actually 172, some
are included more than once, determined by setting CPPFLAGS to contain -H):

So it might be likely that to build the SVG module libiconv and libxml could be
the extra requisites, but /sw/include/iconv.h is also used for coders/msl.c
and coders/url.c; /sw/include/libxml2/libxml/HTMLparser.h,
/sw/include/libxml2/libxml/chvalid.h,
/sw/include/libxml2/libxml/parserInternals.h for coders/msl.c; etc. The file
coders/msl.c handles the execution of "Magick Scripting Language Scripts", so
it's a piece of ImageMagick's core.
IMO there is no extra effort and there are no extra dependencies in building
ImageMagick's SVG module. They arise when Cairo or librsvg are used as
delegates to read and write SVG files.
