LINK_WHAT_YOU_USEΒΆ
Added in version 3.7.
This is a boolean option that, when set to TRUE, adds a link-time check
to print a list of shared libraries that are being linked but provide no symbols
used by the target. This is intended as a lint.
The flag specified by CMAKE_<LANG>_LINK_WHAT_YOU_USE_FLAG will
be passed to the linker so that all libraries specified on the command line
will be linked into the target. Then the command specified by
CMAKE_LINK_WHAT_YOU_USE_CHECK will run after the target is linked
to check the binary for unnecessarily-linked shared libraries.
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.
