You may try:
#+header: :includes '("<iostream>" "<ginac.h>")

I notice that
https://orgmode.org/worg/org-contrib/babel/languages/ob-doc-C.html
only has examples of a single library being using in :includes
parameter.

Although the text description does mention list of strings, it would be
nice if there was an example using :includes with multiple libraries
and/or local libraries.
