you should be able to use part of the CXXCOM (or CCCOM) variable 
definition, which compiles the single include paths as given by $CPPPATH 
into a fully expanded list of "-I/include_folder1 -I/include_folder2".
Try adding something like "$_CPPINCFLAGS" to your CppCheck command.

Yes, it is possible to derive your own Scanner class from the default 
ones, and then install them instead. Can you tell us a little bit more 
about what you are trying to accomplish?
