       the lite-xl binary via a symlink, like typically done by Homebrew:

    /usr/local/bin/lite-xl -> /Applications/lite-xl.app/Contents/MacOS/lite-xl

       The resourcePath returns /usr/local in this case instead of
       /Applications/lite-xl.app/Contents/Resources, which makes later
       access to the resource files fail. Resolving the symlink to the
       executable and then the relative path to the expected directory
       Resources is a workaround for starting the application from both
       the launcher directly and the command line via the symlink.
