LVRIOEval_C_Exercise1 Eclipse project missing include files

[argolds]

I am trying to get started with C++ programming in the RIO RT so I am going through the C++ tutorial.  Everything is working fine up to exercize 1 step 10 where you adjust the values but then I notice that the C header file locations are unresolved so I am unable to build the changes project:

Can someone show me how to resolve these missing files?  Perhaps I missed a step in my setup of the tools?

<edit>  I just noticed the project explorer paths are absolute:

  However right clicking on the "includes" folder does nothing and I cannot determine how to change these paths.
