INJECTOR_GVM_HAS_TRANSLATOR
If defined, the user should provide their own address_manager::translator function.
That function is responssible for translating a void pointer (that mayn't be an actual pointer) into an actual address.
The meaning of that void pointer will be made by YOU when you send it to the functions that receive pointers on this library.
The default translator does nothing but returns that void pointer as the address.
INJECTOR_GVM_OWN_DETECT
If defined, the user should provide it's own game detection function thought game_version_manager::Detect
By default it provide an good detection for the Grand Theft Auto series.
INJECTOR_GVM_PLUGIN_NAME
If this is defined, it will be used as the plugin name used at error messages.
By default it will use ""Unknown Plugin Name"
INJECTOR_GVM_DUMMY
If defined, the game_version_manager will be a dummy object
By default it provides a nice gvm for Grand Theft Auto series
INJECTOR_OWN_GVM
If defined, the game_version_manager should be implemented by the user before including this library.
