Since commit 458ea9d76c (XL: Add C++14 language level flags, 2019-04-15, v3.15.0-rc1~226^2) we use `-qlanglvl=extended1y` for C++14 with XL 16.1. However, that flag is only supported on a Linux host. Issue: #20521

-----------------
Disallowed since version 3.0. See CMake Policy :policy:`CMP0035`.
Use the :command:`if` command instead.
Assert satisfaction of an option's required variables.
::
variable_requires(TEST_VARIABLE RESULT_VARIABLE
REQUIRED_VARIABLE1
REQUIRED_VARIABLE2 ...)
The first argument (``TEST_VARIABLE``) is the name of the variable to be
tested, if that variable is false nothing else is done. If
``TEST_VARIABLE`` is true, then the next argument (``RESULT_VARIABLE``)
is a variable that is set to true if all the required variables are set.
The rest of the arguments are variables that must be true or not set
to ``NOTFOUND`` to avoid an error. If any are not true, an error is
reported.
