# build blender dependencies
# - usd 21.02 fails on ARM. bump the version to 21.08 and remove the failing diff patch
# - blosc 1.5.0 fails to compile on ARM. bump the version to 1.5.4
# - most ARM do not support SIMD, so we disable it if on those CPUs
# - replace make with ninja for speed (though they're likely similar)
