If you want to use Emacs on one of the alternative window systems
available on GNU/Linux and some Unix systems, such as Wayland or
Broadway, you can install the PGTK port of Emacs, which utilizes the
GTK+ toolkit to support them, by passing '--with-pgtk' to configure,
like this:
Broadway, you can build the PGTK ("Pure GTK") port of Emacs, which
utilizes the GTK+ toolkit to support those window systems. To this
end, invoke the configure script with the '--with-pgtk' option, like
this:
./configure --with-pgtk
Keep in mind that the only toolkit which will work with this option is
GTK+ version 3, and specifying any X-specific configuration option is an
error when it is enabled.
This build is only supported with GTK+ version 3, and it is an error
to specify any other X-specific configuration option when PGTK is
enabled.
Afterwards, you will be able to switch between running Emacs on X,
Wayland and Broadway using the 'GDK_BACKEND' environment variable.
GTK+ should automatically detect and use the correct value for your
system, but you may have to specify it manually. For example, you
must run Emacs like this to force GTK+ to run under Broadway:

GNUstep also has support for the Wayland window system. If that is what
you want, see nextstep/INSTALL.
