Nice work.

We are missing the documentation api updates ( https://github.com/rapidsai/rapids-cmake/blob/branch-24.08/docs/api.rst ) and the formatting rules ( https://github.com/rapidsai/rapids-cmake/blob/branch-24.08/cmake-format-rapids-cmake.json )

[KyleFromNVIDIA]

Done

[robertmaynard]

It would be great to have a kvikio PR that leverages this work so we can validate we didn't miss anything

[KyleFromNVIDIA]

rapidsai/kvikio#408 was already working on this, I'll update it to use this PR instead.

[KyleFromNVIDIA]

Updated rapidsai/kvikio#408 to use this PR.

[KyleFromNVIDIA]

Also opened rapidsai/cudf#16360 to test this PR.

This is due to how rapidsai/kvikio#408 changes are structured. The setting of the rapids-cmake-repo* variables need to happen on all evaluations of cpp/cmake/rapids_config.cmake

[KyleFromNVIDIA]

Fixed the variable issue at rapidsai/kvikio#408.

[robertmaynard]

Approving, presuming that the cudf and kvikio CI won't show any issues

[KyleFromNVIDIA]

rapidsai/kvikio#408 is now passing CI

[KyleFromNVIDIA]

rapidsai/cudf#16360 is passing CI too. Ready to merge?
