I am using Agx Orin, Jetpack version 5.1.2，When I was compiling, I encountered this issue。

In Jetpack 5.1, the interface has changed. How should I modify it

[geoncoder]

Any update on this issue? Ran into the same problem.

I think you can ignore the option "nvmpi" and try "--enable shared --disable static" cmd.

I don't know the influence of missing "nvmpi", but my method can be compiled successfully .

Hope any update...I also met such problem on jetson orin nx， but successfully compile on jetson xavier nx。。。
Strange..

https://blog.csdn.net/cnrgq2010/article/details/135130020 这个博客里面提到了，可以删掉CMakelist.txt中的lib_nvbuf相关的内容，就可以正常编译了。。。这个是因为Jetpack版本高于5.1.1后，好像是删除了libnvbuf_utils.so文件了。

这个的issue里面有说明，最好是用完整的一套，如果直接屏蔽掉那句话，会有问题。
由于nvbuf_utils库存在于5.1.2之前的jetpack版本中，
但在此版本中被完全删除。生成不再需要此库如果是Jetpack 5.1.2及其之后的版本，则需要修改CMakeLists.txt，
注释掉 find_library（LIB_NVBUF nvbuf_utils PATHS /usr/lib/aarch64-linux-gnu/tegra
