📝 Walkthrough

Summary by CodeRabbit

• Bug Fixes

  • Improved wheel packaging to correctly handle CUDA-version-specific runtime libraries.
  • Updated build configuration to support the latest RTCX dependency and header layout.

• Chores

  • Refreshed copyright attribution in build tooling.
  • Standardized RTCX integration across the project without changing runtime behavior.

Walkthrough

The wheel repair scripts now handle CUDA-major-specific libraries. The RTCX dependency uses a new revision and include layout. The cuDF wheel script also updates its SPDX notice.

Changes

Wheel repair configuration

Layer / File(s)	Summary
Auditwheel library exclusions ci/build_wheel_cudf.sh, ci/build_wheel_libcudf.sh	The libcudf repair script derives the CUDA major version and excludes matching libnvrtc and libnvJitLink libraries. The cuDF script updates its SPDX notice.

RTCX dependency update

Layer / File(s)	Summary
RTCX source and include paths cpp/cmake/thirdparty/get_rtcx.cmake, cpp/src/jit/cache.cpp, cpp/src/jit/cache.hpp, cpp/src/jit/helpers.cpp	The build fetches RTCX from a new commit, uses the relocated embed module, and updates JIT includes to rtcx/rtcx.hpp.

- Around line 37-39: Add coverage for the wheel exclusion contract used by the
five repair commands, verifying each repaired wheel omits libnvrtc.so,
libnvrtc-builtins.so, and libnvJitLink.so; also add the required unit benchmark
for this build path.
- Around line 37-39: Update the auditwheel exclusion arguments in
ci/build_wheel_cudf.sh lines 37-39, ci/build_wheel_cudf_streaming.sh lines
66-68, ci/build_wheel_libcudf.sh lines 40-42,

lines 42-44 to use wildcard SONAME patterns libnvrtc.so.*,
libnvrtc-builtins.so.*, and libnvJitLink.so.*; also pin auditwheel to version
6.2.0 or newer in each wheel builder.

compatible with CMake 3.30.4, preserving compatibility with the reviewed cuDF
revision and supported CI toolchains; do not raise the cuDF minimum unless no
compatible RTCX commit is available.
