# (c) Copyright 2019-2024 OLX
# We are manually installing and configuring libvips and each required package because previously when trying to use
# the community built bundles (i.e. vips and vips-heif) the performace of Dali has been significantly degraded.

# With the next command, the libvips bianries are copied from the previous stage hence we don't have to install it again.
# The default location where the `configure` script installs libvips is `/usr/local/lib` unless overridden by `--prefix`
# which we don't do.
# !!! Also it's essential for the next `COPY` command to be executed before adding the rest of the packages thus the
# libvips binaries are included in the ldconfig cache.
