Since possibly a recent change, FindCUDAToolkit fails to find the libcupti since it is not looking to
/usr/loca/cuda/include path anymore. Nvidia cuda packages install headers together with the other headers instead of
/usr/local/cuda/extras/CUPTI/ as searched by the package.
$ dpkg -L cuda-cupti-dev-11-4 |grep cupti.h /usr/local/cuda-11.4/targets/x86_64-linux/include/cupti.h

Is it possible to add CUDAToolkit_INCLUDE_DIR to search paths? What is the suggested solution here other than setting the
