Falcor 3.2 Release Compile and Link

[yhyu13]

Hi,

I was trying to build this project today with Falcor 3.2. There were a bunch of compile errors, specifically, the UI handle has changed from addFloatSlider to addFloatVar. Were you using the release version of Falcor 3.2 at your development? In particular, this line cannot be compiled from Falcor 3.2 (both 3.2.0 and 3.2.1) because Falco::Device::desc does not have enableRaytracing? Which version of Falco did you use, is it 3.2.0 or 3.2.1 release https://github.com/NVIDIAGameWorks/Falcor/tags?
