libnvinfer_c is a wrapper around libnvinfer that exports C
functions.
The original TensorRT libraries do not export C functions. They can only be linked to from a C++ application. This library provides an interface to TensorRT over a C ABI. This makes it easier to use TensorRT from other languages.
The CI builds libnvinfer_c on the TensorRT docker image version 25.06
which corresponds to TensorRT version 10.11.0.33 and CUDA version 12.9.1.
