Build cairo-xlib bottle for High Sierra

[npyl]

If someone could build a cairo-xlib for Hight Sierra that would be great.
It would improve TravisCI test time of conky and conky-all and building ManageConky for High Sierra (soon).

How do I build a bottle?
I would really appreciate it, if you first cloned my website, in order to add the bottle there and make a pull request for me to merge it.
Here are the steps:

# clone site
git clone https://github.com/npyl/npyl.github.io

# introduce our conky repo to Homebrew
brew tap Conky-for-macOS/homebrew-formulae
brew update

# build cairo-xlib
brew install --build-bottle cairo-xlib

# package it as a bottle
brew bottle cairo-xlib

You should now have a tar.gz file starting with cairo-xlib on your current directory.

Please write down the message shown by homebrew, it should be sha256 related.

Now, copy that tar file inside npyl.github.io/Projects/Bottles and finally make a pull request.

Don't forget to write here the homebrew message.
Thanks.
