# Ninja, pinned, from the upstream release binary.
#
# Shared by all four build images (docker/*/Dockerfile). The build context is docker/, so each
# Dockerfile reaches this with COPY common/. Version inputs come from that Dockerfile's ARGs.
#
# Pinned for the same reason as CMake: the distro versions span 1.8.2 (EL8) to 1.11.1 (Noble), and
# 1.8.2 is too old to parse what recent Qt generates -- it fails with "multiple outputs aren't
# supported by depslog", which is a ninja limitation lifted in 1.10, not anything wrong with Qt.
#
# The zip is unpacked with python3 rather than unzip: python3 is in every image already and unzip
# is not, so this needs no extra package.
