Configurations specify different ways to build a project. For example, you may configure a project to be in “debug” mode, or perhaps in “release” mode.
The project, and each target type all have a slot named
configuration-variables. To add new variables to a
configuration find this slot in the custom buffer, and insert a new
configuration. Name it either “debug” or “release”, then insert
some number of name/value pairs to it.
You can have any number of valid configurations too. To add a new configuration, customize your project. Work in the ‘[Settings]’ block for “configurations”. Add a new named configuration here.
To switch between different active configurations, modify the “configuration default” slot.
