[BUG] CUDA lineinfo and kernel info is not generated by current cmake build

[vinaydes]

Describe the bug
cpp/CMakeLists.txt has a option to enable generation of CUDA kernel lineinfo on line:

cuml/cpp/CMakeLists.txt

Line 66 in 42297b5

option(LINE_INFO "Enable lineinfo in nvcc" OFF)

However, enabling it does not generate required lineinfo, which is useful for debugging and profiling.

UPDATE: KERNEL_INFO flag is also ignored, see Venkat's comment below.

Steps/Code to reproduce bug
Enable LINE_INFO option in the CMakeLists.txt file and build in verbose mode. See that CUDA compile lines have no -lineinfo option.

Expected behavior
Line information should be generated when enabled.

Environment details (please complete the following information):

• Environment location: I tested on Bare-metal, but should be reproducible on Docker, Cloud etc.
• Linux Distro/Architecture: Not relevant
• GPU Model/Driver: Not relevant
• CUDA: Not relevant
• Method of cuDF & cuML install: from source
  • cmake version 3.20.2 & gcc/g++ version 9.3.2

Additional context
This issue is probably because the module

cuml/cpp/cmake/modules/ConfigureCUDA.cmake

Line 37 in 42297b5

if(CUDA_ENABLE_LINEINFO)

Looks for variable CUDA_ENABLE_LINEINFO and cpp/CMakeLists.txt sets LINE_INFO. On my local setup changing this produced the line information.

I see the same problem with KERNEL_INFO here

cuml/cpp/CMakeLists.txt

Line 65 in 42297b5

option(KERNEL_INFO "Enable kernel resource usage info" OFF)

The only other place that the variable KERNEL_INFO semems to be used in the file is here:

cuml/cpp/CMakeLists.txt

Line 84 in 42297b5

message(VERBOSE "CUML: Enabling kernel resource usage info: ${KERNEL_INFO}")
