     * @brief Finds the first Client matching the condition expressed by passed in @p func.

     * Internally findClient uses the std::find_if algorithm and that determines how the function
     * needs to be implemented. An example usage for finding a Client with a matching windowId
     * @code
     * xcb_window_t w; // our test window

     * @endcode
     *
     * For the standard cases of matching the window id with one of the Client's windows use
     * the simplified overload method findClient(Predicate, xcb_window_t). Above example
     * can be simplified to:
     * @code
     * xcb_window_t w; // our test window
     * X11Window *client = findClient(Predicate::WindowMatch, w);
     * @endcode

     * returns a value convertible to bool. The value returned indicates whether the
     * X11Window *is considered a match in the context of this function.
     * The function shall not modify its argument.
     * This can either be a function pointer or a function object.
