I solved the build issue I was having with CadReader. I now have a different problem with FbdReader using opencascade 7.6:
:info:build :../../FbdReader/inc/FbdReader.hxx:1074:: 74fatal error:: 'GeomAdaptor_HCurve.hxx' file not found
:info:build fatal error10:10: fatal error: 'GeomAdaptor_HCurve.hxx' file not found
:info:build : 'GeomAdaptor_HCurve.hxx' file not found
:info:build #include <GeomAdaptor_HCurve.hxx>
:info:build ^~~~~~~~~~~~~~~~~~~~~~~~
:info:build #include <GeomAdaptor_HCurve.hxx>
:info:build ^~~~~~~~~~~~~~~~~~~~~~~~
:info:build #include <GeomAdaptor_HCurve.hxx>
:info:build ^~~~~~~~~~~~~~~~~~~~~~~~
:info:build fatal error: 'GeomAdaptor_HCurve.hxx' file not found
:info:build #include <GeomAdaptor_HCurve.hxx>
:info:build ^~~~~~~~~~~~~~~~~~~~~~~~
I found this in the release notes:
> Upgrade to OCCT 7.6.0

> <>Simplification of surface/curve adaptor
>
> Interfaces Adaptor2d_Curve2d <https://dev.opencascade.org/doc/refman/html/class_adaptor2d___curve2d.html>, Adaptor3d_Curve <https://dev.opencascade.org/doc/refman/html/class_adaptor3d___curve.html> and Adaptor3d_Surface <https://dev.opencascade.org/doc/refman/html/class_adaptor3d___surface.html> now inherit Standard_Transient <https://dev.opencascade.org/doc/refman/html/class_standard___transient.html> and can be Handle-managed. No more necessary parallel hiererchy of classes Adaptor2d_HCurve2d, Adaptor3d_HCurve and Adaptor3d_HSurface (generated from generic templates by WOK) has been eliminated. Existing code using old Handle classes should be updated to:
>
> Rename occurrences of old names (remove H suffix); upgrade.bat could be used for that purpose.
> Replace redundant calls to previously declared methods .GetCurve2d()/.GetCurve()/.GetSurface() with the common operator->() syntax.
> Pay attention on code calling GetSurface()/GetCurve() methods of removed handle classes. Such places should be replaced with Handle dereference.
I'll try patching the source.
Thanks,
Mark

Approach 1 runs a lot faster since it does not call on makedependto generate all those header dependencies (which can take some time for a large project). And as mentioned in my previous posts to the Macports mailing list, the compiler typically does NOT need to know about these header dependencies to properly build and link the final binary product for the first time.

The $(INCLUDES) does not need to contain any of the directories where the system headers are located since the compiler knows where they are. And as you found out, the location of the system headers will change from MacOS to MacOS.

The vast majority of time, they are NOT needed to build the initial project. (They are needed if you want to use "make" to rebuild your project properly on subsequent runs where the developer has changed one of more of these system header files. This is not a normal scenario if one is using Macports to build the project).

I would suspect this part of the Makefile was not hand-written but generated with one of the compiler's -M options. To work correctly in that case, it would need to be regenerated for each new system the software is built on.
