下面命令用于将QNN模型（.cpp+.bin)转为动态库（.dll），其中QNN模型（.cpp+.bin)由qnn-onnx-converter生成：
(venv4qnn) PS C:\Users\HCKTest>
python C:\Qualcomm\AIStack\QAIRT\2.22.0.240425\bin\aarch64-windows-msvc\qnn-model-lib-generator -c C:\Users\HCKTest\source\repos\testQnn\testResnet50\model\resnet50-v1-7.cpp -b C:\Users\HCKTest\source\repos\testQnn\testResnet50\model\resnet50-v1-7.bin -o C:\Users\HCKTest\source\repos\testQnn\testResnet50\model -t windows-aarch64

阅读https://learn.microsoft.com/en-us/cpp/build/clang-support-msbuild?view=msvc-170%E5%8F%AF%E7%9F%A5%EF%BC%8CVisual Studio 2022不会找到之前手工安装到系统中的LLVM（clang-cl），而是需要通过visual studio installer(VisualStudioSetup.exe)来安装，具体安装如下所示：

安装完Visual Studio 2022内置的LLVM（clang-c）后，再次执行qnn-model-lib-generator便可正常生成dll库啦：
