# 13 开启 MNN_SEP_BUILD=ON 时，Vulkan/OpenCL 后端会被编译成独立的动态库，但 MNN 官方的 CMakeLists.txt
#没有给这两个后端库添加安装规则，所以 make install 只会复制核心的 libMNN.so，不会自动复制 libMNN_Vulkan.so 和 libMNN_CL.so
#手动复制两个文件如下
# 1. 先确认编译好的库文件存在
ls -lh /opt/openAI/project/MNN-3.5.0/build/source/backend/vulkan/libMNN_Vulkan.so
ls -lh /opt/openAI/project/MNN-3.5.0/build/source/backend/opencl/libMNN_CL.so

# 2. 复制到安装目录的 lib 文件夹
sudo cp /opt/openAI/project/MNN-3.5.0/build/source/backend/vulkan/libMNN_Vulkan.so /opt/openAI/mnn/lib/
sudo cp /opt/openAI/project/MNN-3.5.0/build/source/backend/opencl/libMNN_CL.so /opt/openAI/mnn/lib/

sudo cp /opt/openAI/project/MNN-3.5.0/build/source/backend/vulkan/libMNN_Vulkan.so  /usr/local/lib/
sudo cp /opt/openAI/project/MNN-3.5.0/build/source/backend/opencl/libMNN_CL.so      /usr/local/lib/

# 3. 刷新系统库缓存
