# The giac build system supports --docdir, but the path /usr/share/giac/doc
# is hard-coded throughout the source code, so passing anything else to
# ./configure --docdir just causes problems. Later, we'll put things right.
#
# micropython is for specific use in an upstream project, so is quickjs.
# Note that disabling fltk is not a real option. It just skip autodetection
# but doesn't disable compiling against fltk. png is needed as part of fltk
# support.
#
# As of 1.9.0.25, --{en,dis}able-gui is no op. The only way to
# disable the gui is though --disable-fltk.
