libcairo.so.2: cannot open shared object file: No such file or directory

I'm running into a missing dependency error when building Godot nightlies since October 5th:

Same issue here.

It seems that a new dependency libcairo is needed : https://github.com/AppImage/libappimage/blob/master/cmake/dependencies.cmake#L13

[TheAssassin]

@a12e the line just shows the dependency is searched for, but it's not linked (or at least not supposed to be linked) into appimagetool. It's only required for libappimage.

Will look into it.

[Calinou]

It's possible to install libcairo2 from system repositories to work around this issue, so I've done that in my daily builds system for now. Of course, it should still be fixed as to not require any system dependencies that are not present on base distributions 🙂

[TheAssassin]

@Calinou working it. We have to move some code around a bit, and then will be able to get rid of this unused dependency.

[TheAssassin]

By the way: this is more of an AppImageKit issue. I am working on it code wise, so please any of you open an issue over there and link to it from here. When it's fixed there, we'll rebuild linuxdeployqt's AppImage with the new appimagetool binary, and can close it here, too.

Thanks for solving this @TheAssassin

[TheAssassin]

Oh right, that issue is still open. I already had Travis create a new release with up to date binaries.
