[QST] about ccmake and downloading rapids.cmake

[pkestene]

Currently when using ccmake (instead of cmake), I can't configure the project; after hitting "c" twice, cmake fails with the following error message

CMake Error at CMakeLists.txt:43 (include):
   include could not find requested file:

     rapids-cmake

 CMake Error at CMakeLists.txt:44 (include):
   include could not find requested file:

     rapids-cpm

 CMake Error at CMakeLists.txt:45 (include):
   include could not find requested file:

     rapids-export

 CMake Error at CMakeLists.txt:46 (include):
   include could not find requested file:

     rapids-find

 CMake Error at CMakeLists.txt:49 (include):
   include could not find requested file:

     rapids-cuda

 Auto-detecting GPU architectures since CMAKE_CUDA_ARCHITECTURES not defined
 CMake Error at CMakeLists.txt:52 (rapids_cuda_init_architectures):
   Unknown CMake command "rapids_cuda_init_architectures".

 Configuring incomplete, errors occurred!

In the top-level CMakeLists.txt, if I change

if(NOT EXISTS ${CMAKE_BINARY_DIR}/RAPIDS.cmake)
    file(DOWNLOAD https://raw.githubusercontent.com/rapidsai/rapids-cmake/branch-21.12/RAPIDS.cmake
         ${CMAKE_BINARY_DIR}/RAPIDS.cmake)
       include(${CMAKE_BINARY_DIR}/RAPIDS.cmake)
endif()

into

if(NOT EXISTS ${CMAKE_BINARY_DIR}/RAPIDS.cmake)
    file(DOWNLOAD https://raw.githubusercontent.com/rapidsai/rapids-cmake/branch-21.12/RAPIDS.cmake
         ${CMAKE_BINARY_DIR}/RAPIDS.cmake)
endif()
include(${CMAKE_BINARY_DIR}/RAPIDS.cmake)

then ccmake configure is OK.

I don't clain, this is a bug, but this is a bit disturbing to me.

thanks @pkestene, this does look like a bug that was introduced recently. Do you want to submit a PR or should we do it?
