@ -159,6 +159,24 @@ If your application is a **user** application, you don't need to add anything in
everything will be automatically generated for you.
The user application will also be automatically be added to the app launcher menu.
Since the list of **user** application is generated by CMake, add a new `option` in the main [CMakeLists.txt file](../../CMakeLists.txt). The application will be built by default if the value is set to `True`. :
```cmake
option(ENABLE_APP_MYAPP "Enable the MyApp application" True)
```
The default value can be overridden by passing an additional parameter to the command line of CMake :
```cmake
$ cmake ... -DENABLE_APP_MYAPP=True ...
```
Then add your **user app** to the list of apps by calling `AddToListIfEnabled()` :
```cmake
AddToListIfEnabled(USERAPP_TYPES_LIST ${ENABLE_APP_MYAPP} "Apps::MyApp")
```
You should now be able to [build](../buildAndProgram.md) the firmware
and flash it to your PineTime. Yay!
