Usage of link_directories is discouraged, and was part of the reason why a target based option was not added. As the documentation for link_directories states "Note that this command is rarely necessary. Library locations returned by find_package() and find_library() are absolute paths. Pass these absolute library file paths directly to the target_link_libraries() command. CMake will ensure the linker finds them."
