Git: xfce4-session refuses to build with --guess-what (disable wayland)

May you please have a look?

make[2]: Leaving directory '/root/rpmbuild/BUILD/xfce4-session-4.19.1/xfsm-shutdown-helper'
make[2]: *** No rule to make target 'xfce-wayland.desktop.in', needed by 'xfce-wayland.desktop'.  Stop.
make[2]: *** Waiting for unfinished jobs....
make[2]: Entering directory '/root/rpmbuild/BUILD/xfce4-session-4.19.1'
/usr/bin/msgfmt --desktop --template xfce.desktop.in -d ./po -o xfce.desktop

make[1]: *** [Makefile:608: all-recursive] Error 1

No wayland! No xfce-wayland.desktop after make dist.
