# the script will build these three libraries from source, even if
# they are installed as part of the host OS since we have seen
# numerous cases where building with random versions (especially older,
# but sometimes also newer versions than recommended here) will lead
# to all kinds of unnecessary pain
#
# it installs the libraries and subsurface in the install-root subdirectory
# of the current directory (except on Mac where the Subsurface.app ends up
# in subsurface/build
