NOTE: Only Gradle versions 7 or higher can be explicitly targeted by a variant, as support for this was only added in Gradle 7.

First, we declare a separate _source set_ and a _feature variant_ for our Gradle 7 plugin variant.
Then, we do some specific wiring to turn the feature into a proper Gradle plugin variant:

_native components_. Each component represents either an executable or a library that Gradle should build. A project can define any number of components. Gradle does not define any components by default.

For each component, Gradle defines a _source set_ for each language that the component can be built from. A source set is essentially just a set of source directories containing source files. For example, when you apply the `c` plugin and define a library called `helloworld`, Gradle will define,...
