# Currently supported:
# _FS_SPILL_BUFFER: Use file backed buffer instead of memory backed one for unshuffling. See `shuffle3.h`.
# Setting the value to `DYN` enables the dynamic buffer, setting it to `MAP` enabled memory-mapped buffer. `MAP` is usually the fastest of the 3 modes.
# DEBUG: Pretend we're building a debug release even though we're not. Will enable additional output messages and may interfere with some optimisations
