 CPU_Z80_DYNAMIC | Needed to build a shared library. Exports the public symbols.
 CPU_Z80_BUILD_ABI | Builds the ABI of type `ZCPUEmulatorABI` declared in the header with the identifier `abi_emulation_cpu_z80`.
-CPU_Z80_BUILD_MODULE_ABI | Builds a generic module ABI of type `ZModuleABI`. This constant enables `CPU_Z80_BUILD_ABI` automatically so `abi_emulation_cpu_z80` will be build too. This option is intended to be used when building a true module loadable at runtime with `dlopen()`, `LoadLibrary()` or similar, and can be accessed retrieving the **weak** symbol `__module_abi__`.
