One of our libcurl ports uses LwIP, using the sockets API provided with
the LwIP library. We had to modify a couple of include files due to
target platform issues, not because of LwIP. Beyond that, I have a
couple of recommendations:
        - Consult with the folks on the LwIP users mailing list, , who can help you
more with the LwIP sockets interface than the libcurl folks.
        - Note that the LwIP sockets interface is not thread-safe. This
is not a problem if libcurl is the only client of the sockets interface,
and if you use the libcurl easy interface.
        - Use the latest LwIP library version. The LwIP folks have
recently fixed some serious issues that we came across using libcurl on
our platform (a testament to using libcurl as a network stack validation

Good luck,
