Unresolved externals when trying to compile

Hi all,

I successfully managed to compile a build of my test project last month, but I am unable to do so now. The only thing codewise that’s really changed is the latest Cesium update I think. I’m getting this error now:

UATHelper: Packaging (Windows (64-bit)): Module.CesiumRuntime.cpp.obj : error LNK2001: unresolved external symbol __CxxFrameHandler4
UATHelper: Packaging (Windows (64-bit)): Module.CesiumRuntime.gen.cpp.obj : error LNK2001: unresolved external symbol __CxxFrameHandler4
UATHelper: Packaging (Windows (64-bit)): Module.CesiumRuntime.cpp.obj : error LNK2001: unresolved external symbol __GSHandlerCheck_EH4

Just to verify, I reinstalled the Cesium Samples project and tried compiling that and it gave me the same error. This is when compiling for 64 bit windows, development config.

Any suggestions?

Thanks!
