building subversion --with-zlib=.... seems to have no effect

Hello there.

I am building subversion from source but always see the output files depend on the system-supplied zlib which is way older than the one I want to use.
What I did was this:

./configure --with-apr=$PREFIX/apr --with-apr-util=$PREFIX /apr-util --with-sqlite=$PREFIX /sqlite

which gives me the error message that subversion requires zlib. So far so good. Then I do

./configure --with-apr=$PREFIX/apr --with-apr-util=$PREFIX/apr-util --with-sqlite=$PREFIX/sqlite --with-zlib=$PREFIX/zlib

which terminates with exit code 0. The messages on stdout look ok, but when I do make and make install, the created libraries will depend on the system-supplied zlib instead of the one I specified to use. Further, in config.log I can see these lines:

...
  $ ./configure --with-apr=$PREFIX/apr --with-apr-util=$PREFIX/apr-util --with-sqlite=$PREFIX/sqlite --with-zlib=$PREFIX/zlib
...
Configured with: ../configure --prefix=/usr --infodir=/usr/share/info --mandir=/usr/share/man --libdir=/usr/lib64 --libexecdir=/usr/lib64 --enable-languages=c,c++,objc,fortran,obj-c++,java,a
da --enable-checking=release --with-gxx-include-dir=/usr/include/c++/4.3 --enable-ssp --disable-libssp --with-bugurl=http://bugs.opensuse.org/ --with-pkgversion='SUSE Linux' --disable-libgcj

...

configure:22585: $? = 0
configure:22585: result: yes

configure:22585: gcc -E -DLINUX -D_REENTRANT -D_GNU_SOURCE -I$PREFIX/zlib/include conftest.c
configure:22585: $? = 0
configure:22585: result: yes
configure:22585: checking for zlib.h
configure:22585: result: yes
configure:22593: checking for inflate in -lz
configure:22618: gcc -o conftest -g -O2 -g -O2 -pthread -DLINUX -D_REENTRANT -D_GNU_SOURCE -I$PREFIX/zlib/include -L$PREFIX/openldap/lib -L/a
ma/wh/bin/Apache-httpd-5451/expat/lib -L$PREFIX/zlib/lib conftest.c -lz >&5
configure:22618: $? = 0
configure:22627: result: yes

So this is confusing for me. While the parameter I passed was recognized and the different checks on zlib were successful, the overall result is --with-system-zlib?

After make and make install, when I check the compiled libraries I get this output:

ldd libsvn_client-1.so
...
        libz.so.1 => /lib64/libz.so.1 (0x00007fc978e9f000)
...

This shows me that the system zlib library is indeed referenced. How would I compile subversion with zlib in a nonstandard location?

Note: the variable $PREFIX does not exist. Instead I work with fully qualified path names but I wanted to save people from reading unnecessary long path names.
