wx Widgets does not link to a valid wx/setup.h

[Clifton B Wood]

I have 3 backends installed on my Ubuntu setup:

base-unicode-3.0
gtk2-unicode-3.0
gtk3-unicode-3.0

However when I try to attempt to integrate my own code using the existing includes package, I get the following error:

In file included from /usr/include/wx-3.0/wx/memory.h:14:
In file included from /usr/include/wx-3.0/wx/defs.h:27:
/usr/include/wx-3.0/wx/platform.h:183:10: fatal error: 'wx/setup.h' file not found
#include "wx/setup.h"
         ^~~~~~~~~~~~

The simple fix was to symlink the proper file as wx/setup.h:

sudo bash -c '(cd /usr/include/wx-3.0/wx; ln -sf /usr/lib/x86_64-linux-gnu/wx/include/gtk3-unicode-3.0/wx/setup.h)'

For the sake of simplyfing things for the user, isn't this something the package can do (also in the case when update-alternatives is used to change the backend!)
