can't compile on linux using g++ 8.3.0 and -std=c++11

../../../optick/src/optick.h:821:193: error: expected primary-expression before ‘)’ token if (OPTICK_CONCAT(autogen_description_, LINE) == nullptr) OPTICK_CONCAT(autogen_description_, LINE) = ::Optick::CreateDescription(OPTICK_FUNC, FILE, LINE, ##VA_ARGS);
^ ../../Source/Callbacks.h:1012:3: note: in expansion of macro ‘OPTICK_EVENT’ OPTICK_EVENT(); ^~~~~~~~~~~~ compilation terminated due to -Wfatal-errors.

I now worked around this by passing a string to OPTICK_EVENT(), as well as other OPTICK_ ... macros.
