Need help with "term does not evaluate to a function taking 1 arguments" error.

[William Aptom]

Hi everyone. I am new the library. 

I stuck at the very beginning. When I JUST include the header file:

#include <opengm/graphicalmodel/graphicalmodel.hxx>

 I received this error message:

accumulation.hxx(95,11): error C2064:  term does not evaluate to a function taking 1 arguments

I am using visual studio 2019 community and I only set the "additional include directory". Why is there an error? Is there any setup I am missing?

Thanks very much for any help!
