Link it against gtk-3.0-wayland instead of both the x11 and wayland
versions, and try again? My nautilus links against 25 X libraries, both
the old-school versions and the xcb async versions. And to wayland libs
as well as Wayland.

It's nearly 8 years later, and the costs of linking to all those
libraries is likely hidden by even the slowest of NANDs, eMMCs or SSD.
Even a stock GNOME install will have all those cached by the OS by the
time you get to launch nautilus.

There might be benefits to reducing the library count, but startup
speed isn't likely to be one.
