The Docker container has installed ccache 4.6 to accelerate the incremental building.
You can change the LOCAL_CCACHE_DIR to a mounted folder so that the cache can persist.
If you don't want to use ccache, you can remove or unset the ccache environment variables.

```bash
unset CCACHE_DIR
unset CMAKE_C_COMPILER_LAUNCHER
unset CMAKE_CXX_COMPILER_LAUNCHER
unset CMAKE_CUDA_COMPILER_LAUNCHER
unset CMAKE_CXX_LINKER_LAUNCHER
```

The first build could take a long time (e.g.: 1.5 hours). Then the rapids-4-spark-udf-examples*.jar is
generated under RAPIDS-accelerated-UDFs/target directory.
The following build can benefit from ccache if you enable it.

If you want to enable building with ccache on your own system,
please refer to the commands which build ccache from the source code in the Dockerfile.
