#39993: FindwxWidgets.cmake: lack of options to find/select the right wxWidgets

---------------------+------------------------------------
 With respect to the ticket #37819 I'm having problems adapting
 {{{plplot}}} to use {{{wxWidgets}}} if {{{wx-config}}} isn't at default
 location.

 I would like to be able to specify the path to {{{${prefix}/lib/wx/config
 /osx_cocoa-unicode-2.9}}} which should be enough to configure everything
 else related to wxWidgets, but I didn't spend enough time to dive deeper
 into the issue, also because {{{plplot}}}'s CMake support is a bit
 suboptimal (I had serious problems using {{{ccmake}}} to configure it).

 This is an upstream bug (I'm not sure which upstream though), but I would
 like to suggest to keep this ticket open until it's fixed upstream if
 possible.

 The port {{{plplot}}} provides {{{cmake/modules/FindwxWidgets.cmake}}}
 which is very similar to the one shipped with {{{cmake}}}. So the ultimate
 point to patch this would probably be {{{cmake}}} and then ask
 {{{plplot}}} developer to fetch an up-to-date file from there.

 Here's a ticket on the {{{cmake}}} bug tracker:
 - http://public.kitware.com/Bug/view.php?id=11296
 It's about a different issue, but it's probably related to the fact that
 the file lacks some features. Ideally a bug report should be sent to that
 tracker, possibly together with a patch.

 A ticket on the {{{wxWidgets'}}} bug tracker has been closed as "'' not a
 wxWidgets bug''":
 - http://trac.wxwidgets.org/ticket/15199
 even though it would probably be nice if {{{wxWidgets}}} would provide
 their own reference implementation of what they deem to be important for
 proper functionality like they do for {{{aclocal/wxwin.m4}}} (that file
 could serve as a role model of what options are needed).


 PS: feel free to change the summary line, I'm not sure how to best
 describe this.
