Only if you are interested in Python, Java, Octave, or Lua.

That definitely should not happen so I suspect there is something
wrong with the way you are using CMake or the version of CMake that
you are using.

I don't have any experience with Cygwin.  Arjen is our expert for that
platform so I assume he will correct anything I say once he becomes
aware of this thread (probably next week since he rarely looks at
PLplot mailing lists on weekends).  But until he can give definitive
replies to your questions, my guess is you are not using the correct
generator for Cygwin.  If I recall correctly what Arjen did, I think
you should be using the "Unix Makefiles" generator instead. Also, one
other Cygwin-related tip I happen to be aware of is make sure you are
using a cmake version that is installed from the Cygwin site rather
than a native Windows version of cmake that you can download from the
Kitware site but which does not work correctly on Cygwin.

In general, Arjen, has gotten most of PLplot to work without issues
on Cygwin so if those two suggestions don't help, don't give up, and
I am sure that Arjen will eventually be able to help you.
