fix(build): resolve cross-platform build configuration errors

- Corrected  signature in  for macOS native builds to match the 5-parameter  definition.
- Conditionally compiled  assignments in  for native builds and removed the  definition for Windows from , resolving 'no member named ' errors in Windows cross-compilation.
- Verified all macOS native build configurations (Debug, Size-Optimized, Final/Strip, Developer/All Options, Tests Only, Tools Only) and the Windows cross-compilation build are now compiling successfully.
