HANDLES not supported by 'clibgen'

I am trying to load a c++ library in to matlab, so that I can use several functions from it. I am using clibgen to execute this.

Since I don't have much experience in C++, I opted to use this function instead of writing wrapper. However, it seems that MATLAB doesnot support c++ Handles. Is there anyway around it?

%%CODE
clibgen.generateLibraryDefinition(headerFiles,"include",includes,"Libraries",libraries,'OutputFolder', outputFolder,'Verbose',true,'PackageName','NurAPI');

%% Error

Did not add 'NurApiCustomCmd' at NurAPI.h:4134.

  'HANDLE' is not a supported type.
