This adds an lws cmake option that builds all the minimal examples as part of lws, it's useful for QA. It adds a macro to examples that depend on a particular lws configuration to understand they should just null out their project definition in builds where the lws configuration requirement is not met, and we are building as part of lws. It also adapts all the example library additions to select the just-built-but-not-yet-installed library in the case it is built as part of lws. If built standalone, it now uses the cmake platform-abstracted way to add the library requirement too. |

lws minimal ws client tx
This demonstrates a ws "publisher" to go with the minimal-ws-broker example.
Two threads are spawned that produce messages to be sent to the broker, via a local ringbuffer. Locking is provided to make ringbuffer access threadsafe.
When a nailed-up client connection to the broker is established, the ringbuffer is sent to the broker, which distributes the events to all connected clients.
build
$ cmake . && make
usage
This example connects to ws-server/minimal-ws-broker, so you need to build and run that in another terminal.
