Bill Hoffman 96242f8022 Add options to run ldd -u -r as a "link-what-you-use" tool
Create a LINK_WHAT_YOU_USE target property and corresponding
CMAKE_LINK_WHAT_YOU_USE variable to enable this behavior.
Extend link commands by running `ldd -u -r` to detect shared
libraries that are linked but not needed.
