I configure as follows:
./configure --with-zlib=/usr/local/include

cc -o sshd sshd.o auth-rhosts.o auth-passwd.o auth-rsa.o auth-rh-rsa.o  
sshpty.o sshlogin.o servconf.o serverloop.o  auth.o auth1.o auth2.o 
auth-options.o session.o  auth-chall.o auth2-chall.o groupaccess.o  
auth-skey.o auth-bsdauth.o auth2-hostbased.o auth2-kbdint.o  auth2-none.o 
auth2-passwd.o auth2-pubkey.o  monitor_mm.o monitor.o monitor_wrap.o kexdhs.o 
kexgexs.o  auth-krb5.o  auth2-gss.o gss-serv.o gss-serv-krb5.o  loginrec.o 
auth-pam.o auth-shadow.o auth-sia.o md5crypt.o  audit.o audit-bsm.o -L. 
-Lopenbsd-compat/ -L/usr/local/include  -lssh -lopenbsd-compat   -lcrypto 
-lrt -lz  -lsecurity -ldb -lm -laud
