Compilation error on Debian 8, Release builds

[Calinou]

I have installed all required dependencies. Operating system is Debian 8 (testing/jessie) 64-bit, Torque3D Git is up-to-date. This is a Release build by the way. Debug builds properly.

This is the output of make (using CMake):

Weird error. Even weirder that it's fine in debug. Wonder if there's a screwy #define somewhere.

The splitting of the scenePolyhedralObject template into two headers is problematic for some compilers - I've run into link errors like this when building with clang-cl.

You might try adding #include "scene/mixin/scenePolyhedralObject.impl.h" to the offending cpp files, which helped fix errors for me. We should probably just merge the two headers, unless there is some compelling reason not to.

Do seem to recall at one point AccumulationVolume was spitting compiler warnings out related to the template. Doesn't seem present this end with a draw-down of a fresh devhead though for confirmation that that would be an additional indicator of the underlying flaw...
