CalcBoneVertInfos() Identifier not found

So I’m trying to use CalcBoneVertInfos() like this

	CalcBoneVertInfos
	(
		Mesh->SkeletalMesh,
		RV_BoneVertexInfos,
		true
	);

However this is what I get:

 Error	C3861	'CalcBoneVertInfos': identifier not found

 Error (active)	E0020	identifier "CalcBoneVertInfos" is undefined

I have included “MeshUtilities.h” in my header. I’m only just starting out with C++ though so I may have done somehting stupid!
