CMP0206 — CMake 4.3.3 Documentation

# CMP0206

Added in version 4.3.

The `CPack Archive Generator` defaults to UID 0 and GID 0.

In CMake 4.2 and below, the `CPack Archive Generator` always used the current user's UID/GID in archive entries. CMake 4.3 added the `CPACK_ARCHIVE_UID` and `CPACK_ARCHIVE_GID` variables to control them. If either is set, the default for the other is `0`. If neither is set, CMake 4.3 and above prefer to default both UID and GID to `0` so that unpacking by `root` produces paths owned by `root`. This policy provides compatibility with projects that have not been updated to expect the new behavior.

The `OLD` behavior for this policy is to produce archive entries with the current user's UID/GID by default. The `NEW` behavior for this policy is to produce archive entries with the UID/GID set to 0/0 by default.

This policy was introduced in CMake version 4.3. It may be set by `cmake_policy()` or `cmake_minimum_required()`. If it is not set, CMake does not warn, and uses `OLD` behavior.

See documentation of the `CMAKE_POLICY_WARNING_CMP0206` variable to control the warning.

Note

The `OLD` behavior of a policy is deprecated by definition and may be removed in a future version of CMake.
