Can't build without Wayland

[tarnh]

 * Xreader version 2.4.2
 * Distribution - Arch

Issue
It's impossible to build xreader without Wayland.

I don't need wayland and use a mesa build without it (but otherwise the default ArchLinux package).

../libdocument/ev-document-misc.h:32:10: fatal error: gdk/gdkwayland.h: No such file or directory

Try removing the gdk/gdkwayland.h includes in libdocument/ev-document-misc.h as we don't support non standard use.
