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 deaddrop
This demonstrates how you can leverage the lws deaddrop plugin to make a secure, modern html5 file upload and sharing application.
The demo is protected by basic auth credentials defined in the file at ./ba-passwords - by default the credentials are user: user1, password: password; and user: user2, password: password again.
You can upload files and have them appear on a shared, downloadable list that is dynamically updated to all clients open on the page. Only the authenticated uploader is able to delete the files he uploaded.
Multiple simultaneous ongoing file uploads are supported.
build
To build this standalone, you must tell cmake where the lws source tree ./plugins directory can be found, since it relies on including the source of the raw-proxy plugin.
$ cmake . -DLWS_PLUGINS_DIR=~/libwebsockets/plugins && make
