### Forward Compatibility
To build samples with new CUDA Toolkit(CUDA 13.0 or later) and UMD(version 580 or later) and old KMD(version 535 or earlier)，you need to set the `CMAKE_PREFIX_PATH` for using new driver library, the command might like this:
```
cmake -DCMAKE_PREFIX_PATH=/usr/local/cuda/lib64/stubs/ ..
```
## Running All Samples as Tests
It's important to note that the CUDA samples are _not_ intended as a validation suite for CUDA. They do not cover corner cases, they do not completely cover the
