/usr/bin/ld: cannot find -lcudart

系统：Ubuntu20.04

CUDA：11.4

编译程序时，已经完成100%了但是最后突然报错如下

/usr/include/aarch64-linux-gnu/NvInferRuntime.h:682:25: note: declared here
  682 |     TRT_DEPRECATED void destroy() noexcept
      |                         ^~~~~~~
[100%] Linking CXX executable yolov8-pose
/usr/bin/ld: cannot find -lcudart
collect2: error: ld returned 1 exit status

看来是无法链接到cudart库，使用find命令在根目录查找该库的位置

cd /
sudo find . -name "libcudart.so"

查找到该库的位置在如下地方：

user@user-desktop:/$ sudo find . -name "libcudart.so"
[sudo] password for leedarson: 
find: ‘./run/user/1000/doc’: Permission denied
find: ‘./run/user/1000/gvfs’: Permission denied
./usr/local/cuda-11.4/targets/aarch64-linux/lib/libcudart.so
user@user-desktop:/$

使用软连接将该库添加在/usr/lib/目录下，命令如下

sudo ln -s /usr/local/cuda-11.4/targets/aarch64-linux/lib/libcudart.so /usr/lib/libcudart.so

随后再重新编译，该问题解决。
