| # mimalloc is always vendored (no system lookup); Arrow downloads its source | ||
| # via FetchContent at build time, which fails on air-gapped compute nodes. | ||
| # The ~mimalloc variant allows disabling it for such environments. | ||
| # Note: oneapi@2025: also has a compiler bug requiring MIMALLOC=OFF regardless. |

When building on an air-gapped system, it turns out arrow does a FetchContent at CMake time.
This PR adds the ability to do
~mimallocto bypass mimalloc.
