I think this is a very reasonable limitation.

What if we did something like this?

* Run a "./preflight" script/executable if it exists.  This could call an external build system.  Alternatively the path to the preflight script could be specified in Package.swift
* Define a particular folder like include/ that we pass as `-I include/` if it exists.

Then "preflight" can create that folder in some way–whether that is copying header files around or what–and have it be included in the include paths.

That way the include path is internal to the package sandbox.
