Andy Green b3131fdfdd cmakelist: Augean Stables refactor 
Establish a new distributed CMake architecture with CMake code related to
a source directory moving to be in the subdir in its own CMakeLists.txt.
In particular, there's now one in ./lib which calls through to ones
further down the directory tree like ./lib/plat/xxx, ./lib/roles/xxx etc.

This cuts the main CMakelists.txt from 98KB -> 33KB, about a 66% reduction,
and it's much easier to maintain sub-CMakeLists.txt that are in the same
directory as the sources they manage, and conceal all the details that that
level.

Child CMakelists.txt become responsible for:

 - include_directories() definition (this is not supported by CMake
   directly, it passes it back up via PARENT_SCOPE vars in helper
   macros)

 - Addition child CMakeLists.txt inclusion, for example toplevel ->
   role -> role subdir

 - Source file addition to the build

 - Dependent library path resolution... this is now a private thing
   in the child CMakeLists.txt, it just passes back any adaptations
   to include_directories() and the LIB_LIST without filling the
   parent namespace with the details

lws minimal http server multivhost

This creates a single server that creates three vhosts listening on both :7681 and :7682. Two separate vhosts share listening on :7682.

vhost listens on port serves
localhost1 7681 ./mount-origin-localhost1
localhost2 7682 ./mount-origin-localhost2
localhost3 7682 ./mount-origin-localhost3

Notice the last two both listen on 7682. If you visit http://localhost:7682, by default you will get mapped to the first one, localhost2.

However if you edit /etc/hosts on your machine and add

127.0.0.1 localhost3

so that you can visit http://localhost3:7682 in your browser, lws will use the Host: localhost3 header sent by your browser to select the localhost3 vhost for the connection, and you will be served content from ./mount-origin-localhost3

build

 $ cmake . && make

Commandline option Meaning
-d Debug verbosity in decimal, eg, -d15
--die-after-vhost For testing failure handling
