cuda lib64和stubs目录下存在同名so 引起cmake错误

该提示显示cuda_add_library错误，但是实际上错误发生在 target_link_libraries链接时

set(CUDA_LIB_DIR ${CUDA_TOOLKIT_ROOT_DIR}/lib64)
file(GLOB_RECURSE CUDA_ALL_LIBS ${CUDA_LIB_DIR}/*.so)

file(GLOB_RECURSE CU_SOURCES *.cu)
file(GLOB_RECURSE CPP_SOURCES *.cpp)
cuda_add_library(test SHARED
${CU_SOURCES}
${CPP_SOURCES}
)
target_link_libraries(gh2nvcodec -lstdc++fs ${CUDA_ALL_LIBS})

可以看到我很粗暴地链接所有cuda的所有lib，但是/usr/local/cuda/lib64目录下还有一个stubs目录，此目录下存在的so与lib64目录下的so同名，因此target_link_libraries出错，所以遍历/usr/local/cuda/lib64下so时需要把stubs下的so去掉，增加以下两句可以达到此效果

file(GLOB_RECURSE CUDA_STUBS_LIBS ${CUDA_LIB_DIR}/stubs/*.so)
list(REMOVE_ITEM CUDA_ALL_LIBS ${CUDA_STUBS_LIBS})
