Actually, I bumped to 5.3.1 for the reason given in the commit message
for 536f94b.  I also added some test infrastructure for pyqt5 with
good build and run-time results (commit 10fe84b).  So I have now
cleared out the easy Qt5 topics, and the only topic left for me on the
Qt5 agenda is the fairly difficult one of converting to the latest Qt5
support method.

Same goes...

@Pedro: could you try the latest git version of PLplot with your
plain/keyword target_link_libraries fixes only?  I am interested to
know whether the bump of the minimum acceptable Qt5 version from 5.2.0
to 5.3.1 solves your version consistency issue with a much later
version of Qt5, and that requested test should answer that question.
By the way, I also tried locally decrementing the minimum version to
5.0.0 as an experiment, but that detected 5.3.2 (my system version of
Qt5) with no issues.  So I still don't understand why you were having
that version inconsistency issue when the minimum acceptable Qt5
version number was set to 5.2.0, but maybe setting it to 5.3.1 as in
the latest git master branch will solve that.
