Thanks for that one.

Sigh.  This keeps coming back and back and back.
Adding -lX11 fixes most linux installations but breaks everyone else.

See for example https://sourceforge.net/p/gnuplot/bugs/1764/

The problem comes from API breakage in wxgtk3.  But not all
platforms use gtk to support wxWidgets.  It is basically
impossible to autodetect whether the locally installed
wxWidgets does or does not require this extra flag.
So instead we note the problem prominently in the Release Notes.
It is the first item in KNOWN ISSUES.
