##### options comments ##########################

# WITH_T1LIB   affects kpdf
# WITH_T1LIB   description adds support for t1lb, a library for decoding
#                          t1 fonts. If it is disabled or missing the freetype
#                          library is used as a fallback implementation.
#                          It is safe to disable this option. You shouldn't
#                          lose any end-user functionality.
# WITH_PAPER   affects kpdf
# WITH_PAPER   description this library is only used to set some default
#                          parameters of paper according to system settings.
# WITH_TIFF    affects tdefile-plugins(tiff)
# WITH_OPENEXR affects tdefile-plugins(exr)
# WITH_PDF     affects tdefile-plugins(pdf dependencies/poppler-tqt)

# NOTE: It seems that libtiff was planned to be used in
#       kviewshell(plugins/djvu) but isn't yet implemented
