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 raw netcat
This example shows to to create a "netcat" that copies its stdin to a remote socket and prints what is returned in stdout.
It has some advantage over the real netcat, it will wait 1s after stdin closes to print results that are in flight.
build
$ cmake . && make
usage
$ echo -e -n "GET / http/1.1\r\n\r\n"| ./lws-minimal-raw-netcat

Note the example does everything itself, after 5s idle the remote server closes the connection after which the example continues until you ^C it.
