# Adds assimp to the orcacad-deps image.
#
# WHY THIS EXISTS. OrcaSlicer mainline gained `find_package(assimp REQUIRED)` in
# src/libslic3r/CMakeLists.txt (glTF/GLB/FBX import for texture-to-colour), and the baked
# orcacad-deps image predates it: the image's deps/ tree has no Assimp directory at all, and
# nothing named assimp exists anywhere in it. On the host, deps/build/dep_Assimp-prefix has
# only `patch` and `update` stamps -- no build, no install -- so the dependency was fetched
# and then never built, in the image or out of it.
#
# The consequence was that scripts/CAD/run-kernel-tests.sh failed at CMake CONFIGURE time,
# before a single source file compiled, so THIS FORK'S KERNEL SUITE COULD NOT RUN AT ALL.
# Every kernel change ported here was parity-checked against snaporca and never independently
# tested (snaporca-w80c). The Snapmaker fork does not hit this: its base requires neither
# assimp nor OpenCV.
#
# WHY A LAYER AND NOT A FULL DEPS REBUILD. Rebuilding every dependency takes hours and would
# rewrite artifacts that are currently working. This adds exactly the one missing package on
# top of the existing image, and it is a Dockerfile rather than a `docker commit` so that what
# was done is reviewable and repeatable instead of being an undocumented mutation.
#
# The flags below are copied from the project's own recipe (deps/Assimp/Assimp.cmake) plus the
# standard superbuild arguments from orcaslicer_add_cmake_project (deps/CMakeLists.txt:158) and
# DEP_CMAKE_OPTS (deps/deps-linux.cmake). Keep them in step with that recipe: this file is a
# stand-in for the superbuild, not an independent opinion about how to build assimp.
#
#   BUILD (from the repo root, tarball already in deps/DL_CACHE/Assimp/):
#     docker build -f scripts/Dockerfile.deps-assimp -t orcacad-deps .
#
#   VERIFY:
#     docker run --rm orcacad-deps sh -c \
#       'ls /OrcaSlicer/deps/build/destdir/usr/local/lib/cmake/assimp*'
#     scripts/CAD/run-kernel-tests.sh
#
FROM orcacad-deps

# v5.4.3 is the version deps/Assimp/Assimp.cmake selects for CMake >= 3.22 (the image has
# 3.28.3). The SHA256 is that recipe's URL_HASH, verified against the cached tarball before
# this file was written -- an unverified archive is not a dependency, it is whatever was
# sitting in the cache.
