+# Mirrors the Linux leg of upstream's .github/workflows/wheel.yml (called from
+# pr_and_main.yml/release.yml): a scikit-build-core/CMake/pybind11 build, with
+# lib/cmake/scipp-cpm.cmake fetching llnl/units, Boost headers, Eigen3, GoogleTest and
+# oneTBB at configure time. GoogleTest is test-only and never installed into the wheel;
+# units/Boost/Eigen3 are statically compiled in, and oneTBB's libtbb.so ships inside the
+# wheel (scipp/lib64/libtbb.so). musllinux is skipped upstream too (`skip = ["*musllinux*"]`
+# in pyproject.toml).

+From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
+From: Ludovic Henry <git@ludovic.dev>
+Date: Tue, 13 Oct 2026 00:00:00 +0200
+Subject: [PATCH] Widen license-files to cover vendored CPM dependencies
+
+pyproject.toml declares the PEP 639 license-files = ["LICENSE"] as an
+explicit list, so scikit-build-core's default LICEN[CS]E*/COPYING*/
+NOTICE*/AUTHORS* glob never runs and only that one path is ever
+collected. The wheel statically links several dependencies that
+lib/cmake/scipp-cpm.cmake fetches and builds from source for every
+wheel build (llnl/units, Boost headers, Eigen3) and dynamically links
+oneTBB's built libtbb.so into the wheel itself (visible in the
+published wheel as scipp/lib64/libtbb.so). None of those licences ship
+in any published wheel; verified against the real scipp-26.8.0 wheels
+on PyPI, which have the same gap.
+
+Widening the explicit list to also match LICENSE.* lets the build add
+LICENSE.units/LICENSE.boost/LICENSE.eigen/LICENSE.tbb at the project
+root with no other packaging change (GoogleTest, the only other CPM
+dependency, is test-only and never installed into the wheel).
+
