to allow programs that use PLplot to find the drivers should be
clarified. The typical situation should be one where PLplot has been
properly installed (I must admit I seldom do that and work from my
build directory mostly, as my programs are generally ad hoc). I will
try and come up with a concise guide for this. Which will actually
involve the three flavours of Windows environments we currently
support - bare Windows, Cygwin and MinGW-w64/MSYS2. (I hope the
32-bits version of Cygwin and MinGW behave in the same way as the
64-bits one.)

@Arjen: I look forward to those wiki changes.

@Cristiano: note that Arjen is the real Windows expert (I only have
occasional experience with MinGW/MSYS on the Wine version of Windows).
So you should pay close attention to his Wiki changes once he makes
those. Also an issue with my advice (which I realized just this
morning) is it is likely incomplete.  I focussed completely on
command-line builds (e.g., with the "NMake Makefiles" generator). That
advice should be basically correct (since IDE's use the command-line
underneath), but it may need some additions from Arjen (i.e., answers
to your further questions about where is the build tree and where is
the install tree) if you are using a cmake generator for one of the
Windows IDE's.
