Compiling Havok demos

I've downloaded and extracted the Havok demos, but the project has dependency on a folder:

$(HAVOK_SDKS_DIR)/win32/dx/Include

But it didn't set up a HAVOK_SDKS_DIR (there is no installer), and I can't find a win32/dx directory anywhere in the extracted Havok packag开发者_运维百科e.

How can I get the demo files to build? What am I missing?

I fixed this by simply REMOVING all references to $(HAVOK_SDKS_DIR) from the project settings. You don't need it.
