MemoryOutputStream不是PxToolkit的成员

Question

我正在尝试创建一个具有自定义网格的PhysX actor。遵循官方文档：

static const PxVec3 convexVerts[] = {PxVec3(0,1,0),PxVec3(1,0,0),PxVec3(-1,0,0),PxVec3(0,0,1),PxVec3(0,0,-1)};


PxConvexMeshDesc convexDesc;
convexDesc.points.count     = 5;
convexDesc.points.stride    = sizeof(PxVec3);
convexDesc.points.data      = convexVerts;
convexDesc.flags            = PxConvexFlag::eCOMPUTE_CONVEX;
convexDesc.vertexLimit      = 256;

PxToolkit::MemoryOutputStream buf;
if(!cooking.cookConvexMesh(convexDesc, buf))
    return NULL;
PxToolkit::MemoryInputData input(buf.getData(), buf.getSize());
PxConvexMesh* convexMesh = thePhysics->createConvexMesh(input);
PxShape* aConvexShape = aConvexActor->createShape(PxConvexMeshGeometry(convexMesh), aMaterial);

取自the official docs。

但是当我尝试编译时：

error C2039: 'MemoryOutputStream' is not a member of PxToolkit.

我已经包含了使用VS 2013手动构建的PxToolkit.lib文件以及标头。事实上，MOS不在PxTkStream.cpp中。
