未定义参考CUDA和CMake的

Question

我想建立一个小工具，用make的作品，但我想为未来的东西一个cmake的文件。我无法弄清楚链接问题。

cmake_minimum_required(VERSION 3.0) 

PROJECT(vis_3d) 

#find_package(VTK REQUIRED) 
find_package(CUDA REQUIRED) 
find_package(GLEW REQUIRED) 
find_package(GLUT) 
find_package(OpenGL REQUIRED) 

set(CUDA_SEPARABLE_COMPILATION ON) 
set(CUDA_PROPAGATE_HOST_FLAGS OFF) 

set(SOURCE main.cpp) 
set(HEADERS interactions.h) 

set(KERNEL_S kernel.cu device_funcs.cu) 
set(KERNEL_h kernel.h device_funcs.cuh) 

include_directories(${vis_3d_SOURCE_DIR}) 

include_directories(${CUDA_INCLUDE_DIRS} 
        ${OPENGL_INCLUDE_DIRS} 
        ${GLUT_INCLUDE_DIRS} 
        $(GLEW_INCLUDE_DIRS) 
        /usr/local/cuda/samples/common/inc 
        ) 

CUDA_ADD_LIBRARY(device_funcs device_funcs.cu) 
target_link_libraries(device_funcs ${CUDA_LIBRARIES}) 

CUDA_ADD_LIBRARY(kernel_device kernel.cu device_funcs.cu) 
target_link_libraries(kernel_device ${CUDA_LIBRARIES}) 

include_directories(${kernel_device} ${device_funcs}) 

cuda_add_executable(vis_3d 
     ${SOURCE} ${HEADERS} 
     ${KERNEL_h} 
     ) 

#include_directories(${kernel_device} ${device_funcs}) 
target_link_libraries(vis_3d 
     #${VTK_LIBRARIES} 
     ${kernel_device} ${device_funcs} 
     ${CUDA_LIBRARIES} ${OPENGL_LIBRARIES} ${GLUT_LIBRARY} 
     ${GLEW_LIBRARIES} -lglut -lGL -lGLU -lGLEW 
     ) 

错误

不是一个真正的解决方法，但这是由于FindCUDA一个bug（CMake的库CUDA）。它并不适用于可分离编译。 cuda功能的所有定义都在额外的链接阶段中丢失。
