Unfortunately, homebrew does not support --with-universal-ctags option for global (on the state of April 2018)
The reason is that universal-ctags is not officially released yet.
Run brew install --HEAD universal-ctags/universal-ctags/universal-ctags
(See https://github.com/universal-ctags/homebrew-universal-ctags repo)
If you're on macOS, you might have an old ctags installed with command line tools for XCode.
To fix this, simply run alias ctags="`brew --prefix`/bin/ctags"
