# For libjpeg, giflib, libpng, lcms2 and zlib the source is present in the
# OpenJDK repository (referred to as "bundled"). Default is to use libjpeg,
# giflib, libpng and lcms2 libraries as "bundled". The default for zlib is
# to use the bundled zlib on Windows and AIX, otherwise the external ("system")
# zlib, if present. However the libs may be replaced by an external ("system")
# version by the user.
