SOFA libraries/headers/files on different versions

At this time, we are reusing an attaching implementation that was done with an older SOFA version. Some libraries that are called with #include, have been moved from routes, or have a different directory structure.

For example, if I want to call the MechanicalObject.hfile, which it’s located in:

sofa/SofaKernel/modules/SofaBaseMechanics/MechanicalObject.h

I include it of this way:

# include <SofaBaseMechanics/MechanicalObject.h>

It’s OK.

But, I also have the need to include other header files like:

AttachBodyPerformer.h which, I’ve searched and found:

sofa/modules/SofaUserInteraction/AttachBodyPerformer.h, then I include it of this way:

# include <SofaUserInteraction/AttachBodyPerformer.h>

Until here, all O.K

My question is:

How can I recognize what is the way to put the routes to #include…?

When I call to MechanicalObject.h, the #includeinstructions begin at sofa/Sofa/SofaKernel/modules/

but when I did want a call to AttachBodyPerformer.h the #includeinstructions begin at sofa/modules/

I understand that in more recent versions, the libraries and classes can change of location, but …. there is some standard path to find these files type?

Or There is some documentation about it (of change of paths in relation to previous versions? )
This section on documentation will be important, at this moment

I cannot found #include <sofa/component/topology/PointSubset.h> on 17.06 version.

The sofa/component/topology/PointSubset.h is related with topological changes on SOFA, in the 17.06 version … there is some header file/plugin/library which can replace this PointSubset.h functionality?
