Doxygen documenting commented #define

I'm new to Doxygen and recently run into a problem which I could not solve. I have this piece of documented code:

/*!
    \def nAsserts
    Uncomment that line so that all asserts would be removed
*/
//#define nAsserts

and it's supposed to tell the user to uncomment that line when they wish to remove all asserts but doxygen is returning me a warning:

warning: documentation for unknown define nAsserts found

I think the problem is that doxygen ignores all commented codes so is that any way to fix this or work around it?

Not sure if it is a best option, but you can use the approach below.

Modify configuration file to include PREDEFINED parameter:

ENABLE_PREPROCESSING = YES
MACRO_EXPANSION      = YES
EXPAND_ONLY_PREDEF   = YES
PREDEFINED           = "DOXYGEN=1"

In your code, do the following:

#if DOXYGEN
#define nAsserts
#endif

Doxygen follows own preprocessor and can conditionally include/exclude source module sections.
