CMP0099 — CMake 3.25.2 Documentation

# CMP0099

New in version 3.17.

Target link properties `INTERFACE_LINK_OPTIONS`, `INTERFACE_LINK_DIRECTORIES` and `INTERFACE_LINK_DEPENDS` are now transitive over private dependencies of static libraries.

In CMake 3.16 and below the interface link properties attached to libraries are not propagated for private dependencies of static libraries. Only the libraries themselves are propagated to link the dependent binary. CMake 3.17 and later prefer to propagate all interface link properties. This policy provides compatibility for projects that have not been updated to expect the new behavior.

The `OLD` behavior for this policy is to not propagate interface link properties. The `NEW` behavior of this policy is to propagate interface link properties.

This policy was introduced in CMake version 3.17. Use the `cmake_policy()` command to set it to `OLD` or `NEW` explicitly. Unlike many policies, CMake version 3.25.2 does not warn when this policy is not set and simply uses `OLD` behavior.

Note

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