Andy Green 67f532a8c6 cmake: bring tls include requirement out as PUBLIC There's no problem for library build, also with LWS_WITH_MINIMAL_EXAMPLES, but after install at least on OSX, there are problems finding the installed lws include dir (concealed on most platforms by the path being in the default search list for the toolchain), and the references in the lws includes to the tls includes meaning that explicit paths for that must be available at consuming cmakes. This patch enhances the cmake config installed by lws to deal with adding the lws include paths to CMAKE_REQUIRED_INCLUDES and include_directories, so it can be found before the target is introduced. The tls include is passed back up the CMakeLists layers and the lws targets marked with target_include_directories(PUBLIC) with them, so they are understood as needed by consumers. More boilerplate is moved out of the example consuming cmakes. After this, on machines with previous installs of older lws, you may have to clean out the cmake install path, that is usually something like /usr/local/lib/cmake/libwebsockets/* before make installing lws and putting the latest content in there.		2021-10-28 08:12:48 +01:00

lws minimal secure streams server

The application sets up a tls + ws server on https://localhost:7681

It does it using Secure Streams... information about how the server should operate is held in JSON policy in main.c

Visiting the server in a modern browser will fetch some html + JS, the JS will create a ws link back to the server and the server will spam an incrementing number that is displayed in the browser every 100ms.

The app also has a SS client that works, but it's disabled by default since we're interested in server.
