As of commit plplot-5.14.0-21-gc67d153a5 I have bumped our minimum
version of CMake to 3.13.2 and (as requested by Phil and agree with by
me) removed cmake/modules/FindwxWidgets.cmake.

@Arjen:

My apologies to you for the inconvenience this version bump will temporarily
create on the Cygwin and MinGW-w64/MSYS2 platforms since they don't yet
supply CMake 3.13.2 or higher.  However, if you script the required CMake
builds on both platforms, this inconvenience should be minimized.

Feel free to adapt the bash script I have attached which I use for this
purpose.  For example, earlier this morning I invoked this script using

./git_build.sh 3.13.2 yes

to build a local version of the minimum CMake version (now) required by
PLplot which I used to thoroughly test the current set of changes and
which I plan to use for most of my testing from now until the next
CMake minimum version bump.
