[ITK-users] Create ITK Project with CUDA from CMake

[jose alejandro matute flores]

Hi,

I use cuda as well, I have a different directory for my cuda parts of the
application.
What I do is create a static library and link it to the application.
It might not be the best way, but it's been working so far.


 -------------------cuda/CMakeLists.txt ------------------------

FIND_PACKAGE(CUDA REQUIRED)


set (CUDA_NVCC_FLAGS "-g -G -lineinfo" CACHE STRING "nvcc flags" FORCE)


SET (CUDA_VERBOSE_BUILD ON CACHE BOOL "nvcc verbose" FORCE)


SET(LIB_TYPE STATIC)    #set the lib type

CUDA_ADD_LIBRARY(cudaLibName ${LIB_TYPE} visual.h visual.cu )


--------------------------------------------------



and in the main project directory


------- CMakeLists.txt---------------------


find_package(CUDA REQUIRED)

add_subdirectory(cuda)


INCLUDE_DIRECTORIES(${CMAKE_SOURCE_DIR}/cuda)

INCLUDE_DIRECTORIES(${CMAKE_SOURCE_DIR}/cuda/lib)

LINK_DIRECTORIES(${CMAKE_SOURCE_DIR}/cuda)

LINK_DIRECTORIES(${CMAKE_SOURCE_DIR}/cuda/lib)

cuda_add_executable(CUDAitk ${SOURCES}  )


ADD_DEPENDENCIES(CUDAitk cudaLibName)


target_link_libraries( CUDAitk  cudaLibName ....  )


---------------------------------------------


Best,
José
