Did you intend to make this shared by default?

I think that you should use a separate variable (LIBCXX_INCLUDE_DIR perhaps?) that is set to ${CMAKE_CURRENT_BINARY_DIR}/include rather than relying on LLVM's variable.

I realize that this is a standalone build, and therefore LLVM_INCLUDE_DIR *should* point to the same location, but it makes it something that you need to reason out (at least, I had to think about it for a moment).

Is this the format that the rest of the python code in LLVM uses?  I don't really care at the end of the day, just curious.
