version 3.1.0 with 64bit binaries provided by Intel is a part of SDK
embree3.dll built by Intel depends on tbb.dll which depends on msvc[p|r]120.dll
if you use SDK in 32bit, consider building 32bit embree and remove undef in EmbreeCollider.cpp
used for ray-mesh intersections, we can replace it with our own collider if necessary
