The included CMakeLists file is for the 3ds plugin.
My suggestion is to disable the variable shadowing warnings for this project,
since it is basically an external library although included as source files.
The other option is to fix all the variable name reuse for that project, which
feels kind of unnecessary as lib3ds is pretty much abandoned as project (no
activity since 2013). Autodesk has also stopped their development of this
format years ago.
Regards
Björn

Hi François,
I have removed the register keyword usage from
Matrix_implementation.cpp and added the "" to the CMakeLists.txt.
These changes are now checked into git mater.
Robert.
