openssh zlib error

[Koller Bianca (ISS ITO R)]

hi all, 

my system:

hpux 10.20 
zlib 1.1.3  -> /opt/zlib
openssl-0.9.6 ->/opt/openssl

added LD_LIBRARY_PATH /opt/zlib

added PATH /opt/zlib


try to configure openssh

./configure --prefix=/opt/openssh --with-ssl-dir=/opt/openssl


Error: zlib missing


Where can i specify the path where zlib is installed?


regards
