   It looks like `generate_corpuses.sh` is called when `"${ARROW_FUZZING}" == 
"ON"`, but I don't know how to enable `ARROW_FUZZING`.
   
   ```bash
   if [ "${ARROW_FUZZING}" == "ON" ]; then
       # .. snip
   
       # 1. Generate seed corpuses
       # For IPC fuzz targets, these will include the golden IPC integration 
files.
       "${source_dir}/build-support/fuzzing/generate_corpuses.sh" 
"${binary_output_dir}"
   ```    
   
   ```
   
   `ARROW_FUZZING` is enabled in the following parts.
   
   cpp/CMakePresets.json
   
   ```json
       {
         "name": "fuzzing",
         "inherits": [
           "sanitizer-asan",
           "sanitizer-ubsan",
           "base"
         ],
         "displayName": "Debug build with IPC and Parquet fuzzing targets",
         "cacheVariables": {
           "ARROW_CSV": "ON",
           "ARROW_DEPENDENCY_SOURCE": "BUNDLED",
           "ARROW_FUZZING": "ON",
   ```
