You cannot just point the include path at the build tree; the layout of the build tree include files is different from the layout of the include directories when installed.
So, you need to install iulib somewhere, even if it is in /tmp, and then point at that include directory. If you know of a better way of doing this, maybe you can suggest it, but we haven't found one. Making what you suggest work is nice for some environments, but it makes the installed version of iulib messier to use.
