mod_deflate without system zlib

Question

I am building Apache httpd and I want to build it with the module mod_deflate. For this module, I need zlib. So I built zlib on my own. When calling ./configure for Apache httpd, I call it with this parameters:

./configure \
  --enable-deflate \
  ...

After the build has finished, I was looking into the config.log and it says that also the parameter --with-system-zlib was used. Also, when calling ldd mod_deflate after the build, I get this output

    linux-vdso.so.1 =>  (0x00007ffed9ff7000)
    libz.so.1 => /lib64/libz.so.1 (0x00007fab70ba7000)
    libpthread.so.0 => /lib64/libpthread.so.0 (0x00007fab7098b000)
    libc.so.6 => /lib64/libc.so.6 (0x00007fab705bd000)
    /lib64/ld-linux-x86-64.so.2 (0x00007fab70dbd000)

But I want to use my own zlib version. How can I build Apache httpd with my own compiled zlib version and not with the system version of zlib ?
