Describe the bug
We sometimes see the following error messages when configuring cuCollection through rapids-cmake:

-- CPM: Adding package cuco@ (dev)
-- CPM: cuco: Using local package [email protected]

The build still finishes successfully (see NVIDIA/cuCollections#397).

Closing as NVIDIA/cuCollections#404 will remove the usage of the libcudacxx cpm module from cuCOllection
