How to build BOOST 64bit under Windows with libiconv?

I built libiconv as a 64bit DLL for Windows.

I have,

I:\libiconv\src

• iconv.c
• libiconv.rc
• localcharset.c
• localcharset.h
• relocatable.c
• relocatable.h

and

I:\include

• config.h
• iconv.h
• other files

and

I:\libiconv\x64\Release

• libiconv.lib
• libiconv.dll
• Other files

I tried running:

b2 address-model=64 --with-locale -sICONV_PATH=I:\libiconv\

Performing configuration checks

- 32-bit                   : yes (cached)
- arm                      : no  (cached)
- mips1                    : no  (cached)
- power                    : no  (cached)
- sparc                    : no  (cached)
- x86                      : yes (cached)

Building the Boost C++ Libraries.

- iconv (libc)             : no  (cached)
- iconv (separate)         : no  (cached)
- icu                      : no  (cached)
- icu (lib64)              : no  (cached)

Yet, every time iconv is listed as no, so what other magic do I need in this build process?
