Summary by CodeRabbit

• Chores
  • Reduced the maximum allowed compressed package size to shrink the distribution footprint.
  • Excluded deprecated internal dependency paths from built wheels to avoid bundling unnecessary files.
  • Added an unconditional post-install cleanup of transient build artifacts and refined wheel-repair exclusions to streamline published packages and avoid including unwanted files.

Walkthrough

Updated packaging/build scripts to exclude additional papilo artifacts during wheel repair and wheel creation, remove papilo CMake dependency files during conda install, and reduce the compressed-size threshold in pyproject.toml.

Changes

Cohort / File(s)	Summary
Auditwheel / wheel-repair script ci/build_wheel_libcuopt.sh	Modified auditwheel repair exclude patterns: changed libnvJitLink*.so* → libnvJitLink* and added exclusion for libpapilo-core.a.
Conda package install cleanup conda/recipes/libcuopt/recipe.yaml	Added unconditional post-install cleanup: rm -rf "${PREFIX}/lib/cmake/papilo/_deps" to remove vendored papilo CMake dependency files.
Python packaging config python/libcuopt/pyproject.toml	Reduced max_allowed_size_compressed from 900M → 585M. Added [tool.scikit-build].wheel.exclude entries to exclude libcuopt/lib64/cmake/papilo/_deps/** and libcuopt/lib/cmake/papilo/_deps/** from built wheels.

    CI->>Auditwheel: run auditwheel repair (with updated excludes)
    Auditwheel->>Wheel: produce repaired wheel (papilo artifacts excluded)
    Note over Auditwheel,Conda: pyproject.toml size threshold also lowered before packaging

Poem

🐇 I hopped through build scripts in the night,

I nudged out papilo bits just right,
Trimmed the wheel, set size to slim,
A lighter package — cheeky whim! 🥕

Pre-merge checks and finishing touches

✅ Passed checks (4 passed)

Check name	Status	Explanation
Title Check	✅ Passed	The title "Reduce package sizes" directly and clearly summarizes the main objective of the pull request. The code changes consistently target this goal by excluding unnecessary third-party dependency files (papilo), updating auditwheel patterns, and adjusting wheel size thresholds. The title is concise, specific, and accurately reflects the primary change without being vague or generic.
Out of Scope Changes Check	✅ Passed	All changes in the pull request are directly scoped to reducing package sizes by removing unnecessary files. The modifications to ci/build_wheel_libcuopt.sh adjust auditwheel exclusion patterns for papilo libraries, the conda recipe adds cleanup for papilo CMake directories, and pyproject.toml updates wheel exclusion rules and size thresholds—all targeted at eliminating third-party vendored dependencies and reducing overall wheel size. No unrelated refactoring, feature additions, or bug fixes appear to be present.
Docstring Coverage	✅ Passed	No functions found in the changes. Docstring coverage check skipped.
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.

85-87: Broaden the _deps exclusion to cover lib installs too.

CMake can install into either lib or lib64 depending on the platform/toolchain. We now drop ${PREFIX}/lib/cmake/papilo/_deps in the Conda recipe (Line 137), but the wheel exclusion only matches lib64. On platforms where the wheel lands under libcuopt/lib/cmake/..., we’ll still ship the _deps tree and lose the size savings. Please include both possibilities (e.g., add a second pattern for libcuopt/lib/... or use a lib* glob) so the cleanup is reliable across build images.

Apply this diff:

 wheel.exclude = [
-  "libcuopt/lib64/cmake/papilo/_deps/**",
+  "libcuopt/lib64/cmake/papilo/_deps/**",
+  "libcuopt/lib/cmake/papilo/_deps/**",
 ]
