Is this a duplicate?

Type of Bug

Something else

Component

Not sure

Describe the bug

Using CCCL with MSVC and CMake<3.25 produces the following error during CMake configuration:

CMake Error at cccl/CMakeLists.txt:7 (cmake_policy):
  Policy "CMP0141" is not known to this version of CMake.

My CMake version is 3.22, so I believe this also affects the developer build.

How to Reproduce

  1. clone the CCCL repo into some CMake project
  2. add CCCL to the CMake project using add_subdirectory
  3. try to configure the project

Expected behavior

The configuration step of the CMake project should work without producing this error.
