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