LINK_WHAT_YOU_USEΒΆ
Added in version 3.7.
This is a boolean option that, when set to TRUE, will automatically run
contents of variable CMAKE_LINK_WHAT_YOU_USE_CHECK on the target
after it is linked. In addition, the linker flag specified by variable
CMAKE_<LANG>_LINK_WHAT_YOU_USE_FLAG 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.
Note
For now, it is only supported for ELF platforms and is only applicable to
executable and shared or module library targets. This property will be
ignored for any other targets and configurations.
This property is initialized by the value of
the CMAKE_LINK_WHAT_YOU_USE variable if it is set
when a target is created.
