How do I achieve true macro-free code?

[fresh sable]

For example, what would be the C++ way to replace C-style code smells like:

#if (__linux__)
#include <cpuid.h>
#endif

with something along the lines of:

if constexpr (__linux__) {
#include <cpuid.h>
}

obviously this doesn't work, but if there's no cure, what options do I have to avoid macros as much as possible?

honestly this is a fine place for macros

and you kinda have to, as the preprocessor gets run before the compiler

There is no such thing in C++. Also I don't see how the suggestion is an improvement.

in general there is a mantra to avoid macros but that generally refers to using it for codegen imho, this is a perfectly acceptable place for it

or well codegen isn't the proper word, but for making well macros
