brew install qt@5.7 --with-qtwebkit as bottle

Why?

There are some tools, e.g. 'capybara-webkit', that require you to have Qt5 with QtWebKit. Unfortunately, Homebrew does not ship a compiled bottle for Qt with QtWebKit. To install all the required dependencies on macOS, you would have to run brew install qt@5.7 --with-qtwebkit and wait several hours for the whole Qt suite to compile from scratch with QtWebKit.

How to use it?

brew uninstall qt5 qt qt@5.5 qt@5.7
brew install maxfierke/qt/qt57-webkit

And you're good to go. This will install a pre-compiled bottle (currently only on High Sierra).

Troubleshooting

It can't find cmake

cmake is not linked automatically to /usr/local/bin/. Run brew info qt57-webkit to check out the caveats. If it suits your environment, you may just run brew link --force qt57-webkit, though this is not recommended if you're using Qt or qmake to build things outside of Homebrew.

Updating the bottle

Clone this repository and run ./update.sh. It will tell you what to do.
