LWIP doesn't have a makefile because it is not a
standalone application and cannot be used directly in the form it is
distributed.
At a minimum, you need a suitable set of hardware
drivers which allow LWIP to access your network interface,
platform-specific files which integrate into whichever operating system you are
using (or implement the required features if you don't have an operating
system), compiler-specific and platform-specific settings in various header
files, a configuration header file (lwipopts.h) which specifies how LWIP should
operate for you, and an application to actually use LWIP. In some cases you may
need to modify parts of the LWIP source code to fit with how it needs to work
for you.
Therefore your question is still not phrased well
enough for anyone to answer it usefully. What you need is probably a port of
LWIP for the ARM9 platform, which is compatible with your particular compiler,
Ethernet hardware and operating system, and which supports the feature set of
LWIP you need. You haven't specified what any of those are, so nobody can point
you in the direction of an existing port. If there is no compatible
existing port, you will have adapt one for your platform, or create one
yourself.
LWIP has a set of contributed files which include
example applications demonstrating how to use LWIP's various APIs, and example
ports for running LWIP on Windows or Linux
(including makefiles for that environment), which are also useful for testing
your application which will be using LWIP.
A useful resource is the LWIP wiki, at http://lwip.wikia.com/wiki/LwIP_Wiki,
which includes a fair amount of information about how to use LWIP and adapt it
to your platform.
