Subject: add option to find zlib in custom path
X-Git-Tag: v1.5.3-rc4~32

add option to find zlib in custom path

Some systems do not provide zlib development headers and libraries in
default search path of the compiler.  For these systems we should allow
specifying the location by --with-zlib=PATH or by setting ZLIB_PATH in
the makefile.
