Added in version 4.0.
To pass options to the archiver tool, each compiler driver has its own syntax.
The ARCHIVER: prefix and , separator can be used to specify, in a portable
way, options to pass to the archiver tool. ARCHIVER: is replaced by the
appropriate driver option and , by the appropriate driver separator.
The driver prefix and driver separator are given by the values of the
CMAKE_<LANG>_ARCHIVER_WRAPPER_FLAG and
CMAKE_<LANG>_ARCHIVER_WRAPPER_FLAG_SEP variables.
The ARCHIVER: prefix can be specified as part of a SHELL: prefix
expression.
The ARCHIVER: prefix supports, as an alternative syntax, specification of
arguments using the SHELL: prefix and space as separator.
Note
Specifying the SHELL: prefix anywhere other than at the beginning of the
ARCHIVER: prefix is not supported.
