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 ws server raw vhost
This demonstrates setting up a vhost to listen and accept raw sockets. Raw sockets are just sockets... lws does not send anything on them or interpret by itself what it receives on them. So you can implement arbitrary tcp protocols using them.
This isn't very useful standalone as shown here for clarity, but you can freely combine a raw socket vhost with other lws server and client features and other vhosts handling http or ws.
Becuase raw socket events have their own callback reasons, the handlers can be integrated in a single protocol that also handles http and ws server and client callbacks without conflict.
build
$ cmake . && make
usage
-s means listen using tls

Connect one or more sessions to the server using netcat... lines you type into netcat are sent to the server, which echos them to all connected clients.
