[置顶] PCL与CUDA混合编译出现的失败

当在cmakelist中同时含有PCL、CUDA 可能出现一下错误

问题：nvcc fatal   : A single input file is required for a non-link phase when an outputfile is specified

在pcl 下放加入：

get_directory_property(dir_defs DIRECTORY ${CMAKE_SOURCE_DIR} COMPILE_DEFINITIONS)

set(vtk_flags)

foreach(it ${dir_defs})

if(it MATCHES "vtk*")

list(APPEND vtk_flags ${it})

endif()

endforeach()

foreach(d ${vtk_flags})

remove_definitions(-D${d})

endforeach()

问题：消除报警nvcc warning : The 'compute_20', 'sm_20', and 'sm_21' architectures are deprecated, 

使用cmake-gui 设置CUDA_NVCC_FLAGS 为--Wno-deprecated-gpu-targets

cmake -DBLAS=Open -DCUDA_NVCC_FLAGS=--Wno-deprecated-gpu-targets ..
