Detailed Description

A SubProject item is used to add a sub-project that is defined in a separate file. Additionally, properties of the sub-project can be set without modifying the separate project file.

The following example adds a sub-project defined in subdir/project.qbs and overrides its name.

Project {
    SubProject {
        filePath: "subdir/project.qbs"
        Properties {
            name: "A sub-project"
        }
    }
    ...
}

A typical use case for SubProject items is to conditionally include sub-projects. The following example pulls in the tests sub-project if and only if the withTests property is true.

Project {
    property bool withTests: false
    SubProject {
        filePath: "tests/tests.qbs"
        Properties {
            condition: parent.withTests
        }
    }
    ...
}

If you do not need to set any properties on the sub-project, you can also use the Project.references property, the same way you would for a product.

Project {
    references: "subdir/project.qbs"
}

is equivalent with

Project {
    SubProject {
        filePath: "subdir/project.qbs"
    }
}

It is also possible to nest Project items directly in the same file.

Property Documentation

condition : bool

Whether the sub-project is added. If false, the sub-project is not included.

Setting this property has the same effect as setting the condition property within a Properties item. If both this property and the condition property within a Properties item are defined, the sub-project is included only if both properties evaluate to true.

Default: true

filePath : path

The file path of the project to add as a sub-project. If the top-level item in this file is a Product, it gets wrapped automatically in a new project.

Default: empty

inheritProperties : bool

Determines whether the sub-project should inherit the properties of the surrounding Project. You can use this feature to share global settings between projects and sub-projects.

Default: true
