Hi, 
I'm running to a depend= ancy problem with libcurl, libssh2 & libz, mostly related to compabilit= y of libraries.
My libraries is compile with mingW/x86_64 Windows= , here are the configuration command:

./configure --prefix=3D... --with-openssl --disable-examples-build=

which returns this summary:

version: 1.6.0
Host type: x86-pc-mingw32
= Install prefix: ...
Compiler: gcc
Compiler flags: -DLIBSSH2_WIN32 Library types: Shared=3Dyes, Static=3Dyes
Crypto library: Windows Cr= yptography API: Next Generation
Clear memory: yes
Debug build: no Build examples: no
Path to sshd: /bin/sshd (only for self-tests)
= zlib compression: yes

Th= e problem arises when I'm trying to link my application against libssh2-1.d= ll, there was a compability error which returns 0x00007a (load dynamic libr= aires problem). For now I don't know where it come from 
In my application, I only use some curl fu= nction to do a get-file by SFTP, I don't know if I use any of compress= ion functionalities of libz. So I want to get rid of libz if possible to av= oid one more level of dependancy, and yet more of compability problem.

So my question is: Is this possib= le to remove zlib from dependancy when compiling libssh2. If yes, how can I= do that.

Thank you in advanc= e;
Best regards,
