Internal/external packages

Packages are either internal packages or external packages. All packages are considered external packages by default unless explicitly configured as internal through either the package option LIBFOO_INTERNAL or using the project configuration default_internal (see also LIBFOO_EXTERNAL). Both package types are treated the same except for the following:

• An internal package will not generate output warnings if the package is missing hash information or an ASCII-armor.

• An internal package will not generate output warnings if the package is missing licenses.

• When configured for local-sources mode, only internal packages which have local sources configured will have their fetch, extract and patch stages skipped.
