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 cmake_policy command to set it to OLD or NEW explicitly.
