[Bf-committers] Building with openvdb

[Kévin Dietrich]

Hi Dave, 

OpenVDB 4.x has some API breakage, and only OpenVDB 3.x is supported for
now. Will probably make the switch to OpenVDB 4.x for Blender 2.8 since
it is using C++11 by default, and Blender is not yet built with C++11. 

Cheers, 

Kévin
