##############################################################################
# Note: Removed everything related to CUDA_SDK_ROOT_DIR and only left this as
# a possible environment variable to set the SDK directory.
# Include file will be: CUDA_CUT_INCLUDE_DIR
# Cutil library: CUDA_CUT_LIBRARY
##############################################################################
#
#
# CUDA_SDK_ROOT_DIR -- Path to the CUDA SDK. Use this to find files in the
# SDK. This script will not directly support finding
# specific libraries or headers, as that isn't
# supported by NVIDIA. If you want to change
# libraries when the path changes see the
# FindCUDA.cmake script for an example of how to clear
# these variables. There are also examples of how to
# use the CUDA_SDK_ROOT_DIR to locate headers or
# libraries, if you so choose (at your own risk).
