    Found it. For future viewers, on Debian-based systems the package one needs to install is waylandpp-dev. This will install all dev dependencies for Wayland.

    It is all working now - I had to do some finagling using git remote to correct the entries for gerrit to use my userid rather than the email.

    Hi, when your esp device sends data, is it using the same tcp connection or a new one?
    If it is using the same (it is preferred) I suggest you to define an object for each device with a dedicated buffer.
    If not please check if the device wait to have sent all bytes in the queue before to disconnect form the server.
    I made more then one sofwtare based on Qt to manage iot devices based on tcp or rs232.
    I suggest you to use a thread for each connection (if they are not so much, for example less than 1000) or to manage more than one connection for each thread.
    Using a thread, it is more easy to implement a machine state to manage the device.
    Pay attention ad the function readSocket. if the device sends for example 64 byte in one socket operation, the function could be fired more than one time.

    When you want to include some headers of a library you also must pass the include path to the compiler.
    If you use cmake, use target_include_directories() and add the desired include paths there. Later when you use this library (aka you link them with target_link_libraries()), cmake will automatically add the paths specified.

    @Sachin-Bhatt
    It's not a problem, you can ask whatever you wish. And sometimes you will get answers if it's not Qt. Just (a) you didn't get any! and (b) I think your question is so specific/detailed that you need/might be better in a specialist, dedicated forum for this one.

    @ClaraMarieLueders I think you should describe it more specifically
