Building on mbed3
-----------------
MBED3 is a non-posix embedded OS targeted on Cortex M class chips.
https://www.mbed.com/
It's quite unlike any other Posixy platform since the OS is linked statically
in with lws to form one binary.
At the minute server-only is supported and due to bugs in mbed3 network support,
the port is of alpha quality. However it can serve the test html, favicon.ico
and logo png and may be able to make ws connections. The binary for that
including the OS, test app, lws and all the assets is only 117KB.
0) Today mbed3 only properly works on FRDM K64F $35 Freescale Dev Board with
1MB Flash, 256KB SRAM and Ethernet.

1) Get a working mbed3 environment with arm-none-eabi-cs toolchain
(available in Fedora, Ubuntu and other distros)
2) Confirm you can build things using yotta by following the getting started guide here
https://docs.mbed.com/docs/getting-started-mbed-os/en/latest/
3)
git clone https://github.com/warmcat/lws-test-server
and cd into it
4) mkdir -p yotta_modules ; cd yotta_modules
5) git clone https://github.com/warmcat/libwebsockets ; mv libwebsockets websockets ; cd ..
6) yotta target frdm-k64f-gcc
7) yotta install
8) yotta build
