Mike Chemistruck d91e0e4f42 Add POST_BUILD option to ADD_CUSTOM_COMMAND (#5962) 
This commit fixes a set of warnings from the latest version of CMake:

(ADD_CUSTOM_COMMAND):
  Exactly one of PRE_BUILD, PRE_LINK, or POST_BUILD must be given.  Assuming
  POST_BUILD to preserve backward compatibility.

  Policy CMP0175 is not set: add_custom_command() rejects invalid arguments.
  Run "cmake --help-policy CMP0175" for policy details.  Use the cmake_policy
  command to set the policy and suppress this warning.
This warning is for project developers.  Use -Wno-dev to suppress it.

Path to textures defined in MTL files are relative to the MTL
file rather than to the OBJ, so we need to prefix them with the
MTL file directory path.

Julian KnodtandKim Kulling e722420907 [FBX] Allow export multi materials per node (#5888) 
* [FBX] Allow export multi materials per node

Previously it was assumed that each node would export a single material. This removes that
assumption, and also allows for exporting multiple meshes with a single node. Previously they
would each be seprated into their own node.

* Support for animations with multiple meshes too
