libwayland-egl.so could not found

[smoqadam]

Hi,
I tried to create a snake game by this tutorial. When I want to compile it, I get the following error:

thread 'main' panicked at 'Library libwayland-egl.so could not be loaded.', /checkout/src/libcore/option.rs:874:4

I'm using Ubuntu 17.10 gnome
and
piston_window "0.75.0"

this is my stack backtrace:

thread 'main' panicked at 'Library libwayland-egl.so could not be loaded.', /checkout/src/libcore/option.rs:874:4

Make sure you have libwayland-egl-devel installed: sudo apt-get install libwayland-egl-devel

I have the same issue on debian sid latest. All devel packages are installed like libwayland-egl-backend-dev.
