cmssw: kBT_Hex is not a member of TEveBoxSet

Hi,

I am getting the error below while building CMSSW, it is something new which I think was introduced few days ago.

/build/yuka/genreflex/build-cmssw-tool-confv15/CMSSW_10_5_ROOT6_X_2019-01-30-2300/src/Fireworks/SimData/plugins/FWCaloParticleProxyBuilder.cc: In member function 'virtual void FWCaloParticleProxyBuilder::build(const CaloParticle&, unsigned int, TEveElement&, const FWViewContext*)':

    hex_boxset->Reset(TEveBoxSet::kBT_Hex, true, 64);

             hex_boxset->AddHex(TEveVector(centerX, centerY, corners[2]),
                         ^~~~~~
                         AddBox

Checking ROOT TEveBoxSet.h, kBT_Hex is indeed not a member of TEveBoxSet and AddHex neither. I thought the definition in cms fork of ROOT, but they also does not exist there. Could someone give me a bit of context of this code?

Thanks! Yuka - ROOT developer
