          CCExtractor - System Libraries Build
          =====================================

          This build uses system libraries (dynamic linking).

          Required system packages (Debian/Ubuntu):
            sudo apt install libgpac12 libtesseract5 libleptonica6 \
                             libpng16-16 libfreetype6 libutf8proc3

          For HardSubX builds, also install:
            sudo apt install libavcodec60 libavformat60 libswscale7 libavfilter9

          Run with: ./ccextractor --help
