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.

-----------

this module looks for gnuplot



Once done this will define

::

  GNUPLOT_FOUND - system has Gnuplot
  GNUPLOT_EXECUTABLE - the Gnuplot executable
  GNUPLOT_VERSION_STRING - the version of Gnuplot found (since CMake 2.8.8)



GNUPLOT_VERSION_STRING will not work for old versions like 3.7.1.
