[Bf-committers] Alembic broken in blender2.8

[Bastien Montagne]

Currently you cannot build blender2.8 branch with alembic enabled, 
because it still expects particles to be there.

Think ideally, this should be fixed by temporarily disabling particle 
part of alembic code (with a #define e.g.), don't mind trying to do it 
but would be better if someone knowing that code well could tackle this?

Cheers,
