Configure options like

  --with-zlib=/a/dir

are not the right way to tell your compiler where to find the library.

You should use

  CPPFLAGS=-I/a/dir/include LDFLAGS=-L/a/dir/lib configure ...

instead.  Then the value of CPPFLAGS and LDFLAGS are passed to the
compiler when running the tests and you should not have to use
--with-zlib (the configure script will look for zlib by default).
