How to write a function that takes a parameter that is used only if a macro is turned on [duplicate]

I have a function that takes a parameter but that parameter is only used if a certain macro is turned on. e.g.,

void function(bool parameter_for_debug, ....some other parameters used with or without debug turned on....) {
  // do some stuff with other parameters

#ifdef DEBUG
  // do stuff with parameter_for_debug
#endif

}

The problem with this function is you get the unused parameter warning when compiling with DEBUG off.

The current solution I have is to just instead of writing a single function, write function_without_debug and function_with_debug where the former doesn't contain parameter_for_debug and the debug logic, and the latter does (with the macro flags removed). Then in the calling function, I do

#ifdef DEBUG
  function_with_debug(....)
#else
  function_without_debug(....)
#endif

Is there another way to approach this problem? I feel there should be. The problem with my approach is just having some overlap in the two functions.
