# Search in the CUDA_BIN_PATH first.
find_path(CUDA_TOOLKIT_ROOT_DIR
NAMES nvcc nvcc.exe
PATHS ENV CUDA_BIN_PATH
DOC "Toolkit location."
NO_DEFAULT_PATH
)
# Now search default paths
find_path(CUDA_TOOLKIT_ROOT_DIR
NAMES nvcc nvcc.exe
PATHS /usr/local/bin
/usr/local/cuda/bin
DOC "Toolkit location."
)
Following the advice from
http://www.cmake.org/cmake/help/cmake-2-8-docs.html:
The default search order is designed to be most-specific to least-specific
for common use cases. Projects may override the order by simply calling the
command multiple times and using the NO_* options:
find_package(<package> PATHS paths... NO_DEFAULT_PATH)
find_package(<package>)
This is urrr... umm... hokey (calling multiple times). And I cannot seem to
get it to work.
so I set (ouput from my messages below in cmake output window)
CUDA_TOOLKIT_DIR =
C:/projects/NIH2009/source/branches/trunk/source/cpp/lib/3rdParty/Win/CUDA_Toolkit_2.2
NVIDIA_SDK_DIR =
C:/projects/NIH2009/source/branches/trunk/source/cpp/lib/3rdParty/Win/NVIDIA_GPU_Computing_SDK_2.2
by doing:
SET( PLATFORM_DIR platform/3rdParty/Win )
SET( PATCH_DIR platform/3rdParty/patch )
SET( THIRD_PARTY_PACKAGE_DIR source/cpp/lib/3rdParty/Win )
SET( TOOLS_DIR platform/tools )
SET( THIRD_PARTY_SRC_DIR 3rdParty/Win )
SET( APP_SRC_DIR source/cpp/app )
set( DO_LOCAL_CUDA YES )
if( DEFINED DO_LOCAL_CUDA )
SET( CUDA_VERSION 2.2 )
SET( NVIDIA_PACKAGE_DIR
${PLATFORM_DIR}/NVIDIA/GPU_Computing/CUDA_${CUDA_VERSION} )
SET( CUDA_TOOLKIT_DIR
${CMAKE_HOME_DIRECTORY}/${THIRD_PARTY_PACKAGE_DIR}/CUDA_Toolkit_${CUDA_VERSION}
)
SET( NVIDIA_SDK_DIR
${CMAKE_HOME_DIRECTORY}/${THIRD_PARTY_PACKAGE_DIR}/NVIDIA_GPU_Computing_SDK_${CUDA_VERSION}
)
MESSAGE( "CUDA_TOOLKIT_DIR = ${CUDA_TOOLKIT_DIR}")
MESSAGE( "NVIDIA_SDK_DIR = ${NVIDIA_SDK_DIR}" )
unpack( ${NVIDIA_PACKAGE_DIR}/CUDA_Toolkit_${CUDA_VERSION}.zip
${THIRD_PARTY_PACKAGE_DIR} )
unpack(
${NVIDIA_PACKAGE_DIR}/NVIDIA_GPU_Computing_SDK_${CUDA_VERSION}.zip
${THIRD_PARTY_PACKAGE_DIR} )
set( CUDA_TOOLKIT_ROOT_DIR ${CUDA_TOOLKIT_DIR} CACHE STRING "" FORCE )
set( CUDA_SDK_ROOT_DIR ${NVIDIA_SDK_DIR} CACHE STRING "" FORCE )
find_package( cuda PATHS ${CUDA_TOOLKIT_DIR} ${NVIDIA_SDK_DIR}
C:/projects/NIH2009/source/branches/trunk/source/cpp/lib/3rdParty/Win/CUDA_Toolkit_2.2
C:/projects/NIH2009/source/branches/trunk/source/cpp/lib/3rdParty/Win/NVIDIA_GPU_Computing_SDK_2.2
NO_DEFAULT_PATH)
find_package( cuda )
endif()
The line
find_package( cuda PATHS ${CUDA_TOOLKIT_DIR} ${NVIDIA_SDK_DIR}
C:/projects/NIH2009/source/branches/trunk/source/cpp/lib/3rdParty/Win/CUDA_Toolkit_2.2
C:/projects/NIH2009/source/branches/trunk/source/cpp/lib/3rdParty/Win/NVIDIA_GPU_Computing_SDK_2.2
NO_DEFAULT_PATH)
Appears to have no effect, but:
set( CUDA_TOOLKIT_ROOT_DIR ${CUDA_TOOLKIT_DIR} CACHE STRING "" FORCE )
set( CUDA_SDK_ROOT_DIR ${NVIDIA_SDK_DIR} CACHE STRING "" FORCE )
works,but I still get:
cuda_DIR-NOTFOUND
my project successfully builds with only SVN and VisualStudio as the only
host dependency, everything else including cmake, boost,dcmtk, vtk, itk,
gnuwin32 (unzip - why tar, bz2, and gz in cmake but no zip is anyone's
guess, patch, and diff), cuda toolkit, cuda sdk are now all in the svn repo.
Thanks for your help.
