> `link_directories()` treats paths relative to the source dir.

In CMake 2.8.0 and lower the `link_directories()` command passed relative paths unchanged to the linker. In CMake 2.8.1 and above the `link_directories()` command prefers to interpret relative paths with respect to `CMAKE_CURRENT_SOURCE_DIR`, which is consistent with `include_directories()` and other commands. The `OLD` behavior for this policy is to use relative paths verbatim in the linker command. The `NEW` behavior for this policy is to convert relative paths to absolute paths by appending the relative path to `CMAKE_CURRENT_SOURCE_DIR`.

This policy was introduced in CMake version 2.8.1. It may be set by `cmake_policy()` or `cmake_minimum_required()`. If it is not set, CMake warns, and uses `OLD` behavior.

Note

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