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. |
