8c00221f - Fix inconsistent environment variable naming for setting NVTOOLEXT_HOME in TorchConfig.cmake (#48012)

Fix inconsistent environment variable naming for setting NVTOOLEXT_HOME in TorchConfig.cmake (#48012) Summary: When building libtorch with CUDA installed in some unconventional location, CMake files rely on some environment variables to set cmake variable, in particular NVTOOLSEXT_PATH environment variable is used to set NVTOOLEXT_HOME in cmake/public/cuda.cmake. Later when consuming such build using the generated cmake finder TorchConfig.cmake, another convention is used which feels rather inconsistent, relying on a completly new environment variable NVTOOLEXT_HOME, although the former way is still in place, cmake/public/cuda.cmake being transitively called via Caffe2Config.cmake, which is called by TorchConfig.cmake Fixes https://github.com/pytorch/pytorch/issues/48032 Pull Request resolved: https://github.com/pytorch/pytorch/pull/48012 Reviewed By: gchanan Differential Revision: D25031260 Pulled By: ezyang fbshipit-source-id: 0d6ab8ba9f52dd10be418b1a92b0f53c889f3f2d
