This is a boolean option that when set to ``TRUE`` will automatically run
|
|
|
|
|
``ldd -r -u`` on the target after it is linked. In addition, the linker flag
|
|
|
|
|
``-Wl,--no-as-needed`` will be passed to the target with the link command so
|
|
|
|
|
that all libraries specified on the command line will be linked into the
|
|
|
|
|
target. This will result in the link producing a list of libraries that
|
|
|
|
|
provide no symbols used by this target but are being linked to it.
|
|
|
|
|
This is only applicable to executable and shared library targets and
|
|
|
|
|
will only work when ld and ldd accept the flags used.

This property is initialized by the value of
|
|
|
|
|
the :variable:`CMAKE_LINK_WHAT_YOU_USE` variable if it is set
|
|
|
|
|
when a target is created.
