----------------
The reason to use `CMAKE_BINARY_DIR` over `CMAKE_CURRENT_SOURCE_DIR` as the location for this build product is so that the source directory doesn't get polluted by builds.

Unfortunately that means that both libcxx and libcxxabi need to be pointed at the headers in the build directory, and not the ones from the source directory. 

I do have a pair of patches for this, which I'll post shortly.
