Try to reproduce issue rapidsai#1490

I cannot reproduce the linker error. Building with clang 11.1 and nvcc 11.8. Both test files have raft::cache::(anonymous namespace)::get_cache_idx defined though.. $ nm -g -C cpp/build/CMakeFiles/UTILS_TEST.dir/test/util/get_cache_idx_1.cu.o | grep get_cache_idx U __cudaRegisterLinkedBinary_667dac6a_18_get_cache_idx_1_cu_eeb3336e_3832672 0000000000000000 D __fatbinwrap_667dac6a_18_get_cache_idx_1_cu_eeb3336e_3832672 0000000000000010 T __device_stub__ZN4raft5cache59_GLOBAL__N__667dac6a_18_get_cache_idx_1_cu_eeb3336e_383267213get_cache_idxEPiiS2_iiS2_S2_Pbi(int*, int, int*, int, int, int*, int*, bool*, int) 0000000000000000 T raft::cache::(anonymous namespace)::get_cache_idx(int*, int, int*, int, int, int*, int*, bool*, int) $ nm -g -C cpp/build/CMakeFiles/UTILS_TEST.dir/test/util/get_cache_idx_2.cu.o | grep get_cache_idx U __cudaRegisterLinkedBinary_74c80384_18_get_cache_idx_2_cu_a658dc80 0000000000000000 D __fatbinwrap_74c80384_18_get_cache_idx_2_cu_a658dc80 0000000000000010 T __device_stub__ZN4raft5cache51_GLOBAL__N__74c80384_18_get_cache_idx_2_cu_a658dc8013get_cache_idxEPiiS2_iiS2_S2_Pbi(int*, int, int*, int, int, int*, int*, bool*, int) 0000000000000000 T raft::cache::(anonymous namespace)::get_cache_idx(int*, int, int*, int, int, int*, int*, bool*, int)
