Help: How do I enable macros when building on windows?

[futuremotiondev]

I am about to build the engine on windows. I saw the portion in the README about macros:

There are some customizable macros:

    BITTY_MULTITHREAD_ENABLED[=1]: indicates whether project code executes on a thread separately from graphics
    BITTY_DEBUG_ENABLED[=1]: indicates whether project code debug is enabled; requires BITTY_MULTITHREAD_ENABLED==1; disable this to build a pure runner
    BITTY_NETWORK_ENABLED[=1]: indicates whether the Network API is enabled
    BITTY_WEB_ENABLED[=1]: indicates whether the Web API is enabled; disable this if you don't need web accessibility
    BITTY_SPLASH_ENABLED[=1]: indicates whether the splash is enabled
    BITTY_EFFECTS_ENABLED[=0]: whether full screen effects is enabled
    BITTY_PROJECT_STRATEGY_MAP_BATCH_ENABLED[=0]: indicates whether map batch is preferred; it might speed up map rendering if enabled, but requires more memory and could be slow with mset(...)

I want multi-threading enabled, etc.

Where do I set them?

BITTY_MULTITHREAD_ENABLED=1
BITTY_DEBUG_ENABLED=1
BITTY_NETWORK_ENABLED=1
BITTY_WEB_ENABLED=1
BITTY_SPLASH_ENABLED=1
BITTY_EFFECTS_ENABLED=1
BITTY_PROJECT_STRATEGY_MAP_BATCH_ENABLED=1

I read somewhere on google that macros should be defined in project Preprocessor Definitions:

I right clicked on the SDL2 project, expanded the C/C++ submenu, and then selected the Preprocessor entry. In the window on the right, you can edit the Preprocessor Definitions.

This is what I did:

I have a feeling this is wrong though. I am VERY new to C++ (not to coding in general though), and I just want to make sure that the following macros are set before I build:

BITTY_MULTITHREAD_ENABLED=1
BITTY_DEBUG_ENABLED=1
BITTY_NETWORK_ENABLED=1
BITTY_WEB_ENABLED=1
BITTY_SPLASH_ENABLED=1
BITTY_EFFECTS_ENABLED=1
BITTY_PROJECT_STRATEGY_MAP_BATCH_ENABLED=1

Can someone guide me on the correct way to set these macros before the build?

Thanks so much.

The BITTY_* macros are defined within the bitty project, for Visual Studio 2015 (C++) and above, you'll find some of the macros in the project property settings, and most are in the bitty.h header.

The distributed binary was built with multithreading enabled, therefore the app's GUI and execution of game code run on different threads out-of-the-box.
