Hi Arjen:

Thanks very much for that quick turnaround.

from CMake and make, as well as the config header file). We need to
sort out these things before a comprehensive build is going to stand
any chance.

(please generate that next time with VERBOSE=1), it looks like these
build issues have nothing to do with PLplot code and instead are
wxwidgets header incompatibilities _for the compile flags that are
being generated by your current  Unix wxwidgets find method_.

Therefore, I am pretty sure the current build issue is caused by your
build using Unix wxwidgets compile and link flags when it should be
using Windows wxwidgets compile and link flags for the MinGW-w64/MSYS2
platform. So to get access to the latter flags, I suggest you use the
_Windows_ wxwidgets find method (which I understand you automatically
obtain if you use the "MSYS Makefiles" generator.)

If I have understood correctly what you said before, the Windows
wxwidgets find method currently does not work for the MinGW-w64/MSYS2
platform. Nevertheless, since our wxwidgets code with old IPC method
did build correctly on MSVC before with this find method, I assume
whatever correction you have to make to
cmake/modules/findwxWidgets.cmake to get the Windows find method to
work correctly on the MinGW-w64/MSYS2 platform should be quite small.
And as per usual, the cmake options --debug-output --trace are
extremely useful for debugging find modules, but if those are not
sufficient to discover the problem, you can always locally insert
message(...) commands in cmake/modules/findwxWidgets.cmake.

Anyhow, good luck with this debugging of the Windows wxwidgets find
method on MinGW-w64/MSYS2.
