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.  CMake version
|release| warns when the policy is not set and uses ``OLD`` behavior.  Use
the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
