I’d like to build 2 debian packages: A `Runtime` package which has some files and a `Develop` package. Which has ALL the files from the `Runtime` package as well as some additional files.
Is this possible?
With CPack i’d expect the following:
```auto
cpack_add_component_group(RuntimeGroup)
cpack_add_component(Runtime GROUP RuntimeGroup)
cpack_add_component_group(DevelopGroup PARENT RuntimeGroup)
cpack_add_component(Develop GROUP DevelopGroup)
```
This results in 2 debian packages. However the `DevelopGroup` package only contains the stuff from the `Develop` component. The PARENT argument seems to be ignored completely.
Anybody know if it is possible?

PARENT relationships only specify structure, not content. If you need the `Develop` package to contain the contents of `Runtime` (a very unconventional and not recommended arrangement), you would have to install the contents to both the `Runtime` and `Develop` components. It is the `install()` commands that you would have to modify.

Ah, thats good to know!
What would be the more conventional way to solve this? Add Runtime as a dependency to Develop?
The thing i eant to achieve is being able to deploy test tools with a specific runtime and very strict version requirements (e.g. : Runtime 1.0.1 needs Develop 1.0.1).

This is the typical pattern (Debian and Fedora).

The development packages tend to require the exact build too (so `1.0.1-4` in Fedora, not just version number).
