Please expose Math Expression to C++

Please expose something akin to the Math Expression node to C++. I have noticed BasicMathExpressionEvaluator.h and ExpressionParser.h however it’s incredibly difficult to use. I would like to simply pass in lambda or variable addresses, compile the equation ahead of time, and simply call Evaluate throughout the application. I have used something like Exprtk however it is not super viable since need to enable UseRtti.
