Forcing boost to build zlib

Hello,

what is needed to force bjam to build zlib? Is the zlib.h enough?

Also is there a way to make bjam fail compiling if I set "NO_ZLIB=0" and
it does not find the zlib.h / source? It is really inconvenient that
bjam silently switches off zlib without any error or warning why zlib is
not being build. My commands are:

./bootstrap.sh --without-libraries=python
--prefix=/home/simon/code/cfs/release_mingw_openblas/cfsdeps/boost/install
--with-toolset=gcc --without-libraries=context
--without-libraries=coroutine target-os=windows architecture=x86
address-model=64 release

and

./b2 target-os=windows architecture=x86 address-model=64 release
--user-config=user-config.jam toolset=gcc-mingw -s
ZLIB_BINARY=\"/home/simon/code/cfs/release_mingw_openblas/lib64/MINGW_X86_64/libzlibstatic.a\"
-s ZLIB_INCLUDE=\"/home/simon/code/cfs/release_mingw_openblas/include\"
-s NO_ZLIB=0 threading=multi install

(this is cross compiling, but I have the same problem building for Linux)

Regards,
Simon
