@jprotze True, it's not strictly necessary, but the motivation was to help preventing similar issues in the future, since it is easy to overlook that `hwloc.h` is not necessarily included when `KMP_USE_HWLOC` is enabled.

I have tested it with `#define KMP_AFFINITY_SUPPORTED 1` and the fix works for me, but it would still be nice to have confirmation on the platform where the build issue occurs.

Thanks for suggesting `KMP_INCLUDES_HWLOC` as a better name - PR is updated.
