Hum, I'm quite embarrassed, this doesn't work when the block is executed
during an export. I didn't track it down yet, but (buffer-file-name)
returns nil during the export probably because the buffer changes.
A workaround would be to use the :flags header argument though it's a
bit tedious because it doesn't seem possible to eval elisp during the
export.
i.e.
#+BEGIN_SRC cpp :flags -I (file-name-directory (buffer-file-name))
...
#+END_SRC
