# CMP0015

Warning

The `OLD` behavior of this policy was removed in CMake version 4.0. This policy must be set to `NEW` by a call to `cmake_minimum_required()` or `cmake_policy()`.

`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. Prior to removal in CMake version 4.0, it could be set by `cmake_policy()` or `cmake_minimum_required()`. If it was not set, CMake warned, and used `OLD` behavior.
