Develop M1 with C++, Dynamic Lib has missing header files



I never worked with Magician or any other Dobot products before. I am now developing M1 with C++ and I downloaded the “M1 dynamic library v1.0” and included in my project. In the DobotDll.h, it prompted “cannot open source file “dobotdll_global.h”” and “cannot open source file “DobotType.h””. I cannot find these files anywhere in the dynamic library .zip… Am I missing something?

Many thanks.
