=== Variant-dependent Tasks

The {cpp} Library Plugin creates tasks based on variants of the library component.
Read the <<building_cpp_projects.adoc#sec:introducing_build_variants-cpp,introduction to build variants>> for more information.
The following diagrams show the relationship between variant-dependent tasks.
