Build Types:
  --debug                 add extra compile flags for debug builds
  --release               add extra compile flags for release builds

Options:
  --toolkit=(gtk3|cli|gtk2|wpf)
                          The toolkit to use for the UI.

Optional Features:
  --disable-db            Needlessly adds a completely useless SQLite database 
                          by default.
