Inconsistent recommendations for Xwayland installation path and Xwayland load/search path
https://wayland.freedesktop.org/xserver.html proposes installing XServer by running " ./autogen.sh --prefix=$WLD && make && make install". This puts Xwayland under /usr/bin/local. weston searches by default for Xwaywand under XSERVER_PATH which defaults to /usr/bin/Xwayland .
Extend https://wayland.freedesktop.org/xserver.html to recommend putting path=/usr/local/bin/XWayland in [xwayland] in weston.ini or do something different, so that after following the instructions weson finds Xwayland and the web page recommends how to install the X server
