   On my Mac M1 laptop, the compilation looks good but linking complains about undefined symbols:
   ```
   [ 63%] Built target arrow-io-file-test
   [ 63%] Built target arrow-io-memory-test
   [ 63%] Linking CXX executable ../../../debug/arrow-utility-test
   Undefined symbols for architecture arm64:

   ``` 
   
   It looks like I am hitting an old issue: https://stackoverflow.com/questions/58923623/stdto-chars-compile-but-not-linking-on-macos-clang/59672017#59672017
