I threw a post up on the answerhub but I thought I’d open it up to the forums as well.
The details are in the link, but essentially, how can I include the .lib and .dll files that UE4 doesn’t ship with, for a library that it already partially includes? (It has all the .h files, but not the libs and binaries). I.e. TBB is used in UE4 for its allocator, but I wanted to use its other functionality. The answerhub post details the errors I’ve been getting when I modify the IntelTBB-4.0 build file in the /Source/ThirdParty folder.
