[Rtk-users] CMake configuration of CUDA_SDK_ROOT_DIR

[MORY, CYRIL]

Ok, I'll copy-paste the code :)
If, at some point in time, you need to have CMake find the CUDA SDK, you might be interested in knowing that CUDA 5.0 and higher no longer have a cutil.h file. It has been replaced with helper_*.h files, located in the same directory. It's explained in http://stackoverflow.com/questions/12474191/cuda5-examples-has-anyone-translated-some-cutil-definitions-to-cuda5

Regards,
Cyril

Hi Cyril,
We are not using the SDK features. But if you look at FindCUDA.cmake, it does
  find_path(CUDA_SDK_ROOT_DIR common/inc/cutil.h which means that you have to point to the directory containing "common/inc/cutil.h".
But you still have to modify the CMakeLists.txt on the RTK side. This is explained in FindCUDA.Cmake :
# Example of how to find an include file from the CUDA_SDK_ROOT_DIR

# find_path(CUDA_CUT_INCLUDE_DIR
#   cutil.h
#   PATHS ${CUDA_SDK_SEARCH_PATH}
#   PATH_SUFFIXES "common/inc"
#   DOC "Location of cutil.h"
#   NO_DEFAULT_PATH
#   )
# # Now search system paths
# find_path(CUDA_CUT_INCLUDE_DIR cutil.h DOC "Location of cutil.h")

# mark_as_advanced(CUDA_CUT_INCLUDE_DIR)

So far, we have always preferred to copy/paste the code...
Simon
