  38 // simplify builds without CMake, we define these things manually instead of relying on CMake
  39 // to generate the header.
  40 //
  41 // For static builds, our CMakeList will define `ZYDIS_STATIC_BUILD`. For shared library builds,
  42 // our CMake will define `ZYDIS_SHOULD_EXPORT` depending on whether the target is being imported or
  43 // exported. If CMake isn't used, users can manually define these to fit their use-case.
  44
  45 // Backward compatibility: CMake would previously generate these variables names. However, because
  46 // they have pretty cryptic names, we renamed them when we got rid of `GenerateExportHeader`. For
  47 // backward compatibility for users that don't use CMake and previously manually defined these, we
  48 // translate the old defines here and print a warning.
