[CMake] FindwxWidgets.cmake, suggestion add option to pass to wx-config

[Jorgen Bodde]

The wx-config being taken should be the wxWidgets version installed on
your system. If you tweak it by passing options you are forcing
another version which might not work.

Your solution can be handy if there are multiple wxWidgets versions on
your system, but a better way is:

- Compile wxWidgets and use wx-config to specify your options, and add
--prefix=... like

   wx-config --enable-debug --disable-shared
--prefix=/home/jorg/src/wxGTK-ansi-debug-static

- Then build wxWidgets
- Install without root privileges
- Make a shortcut in /usr/local/bin to the config you are currently using

Advantages are:
1) No system pollution because it is installed in your home dir
2) Multiple configs can be easily switched
3) Easy to clean up (simply remove the
/home/jorg/src/wxGTK-ansi-debug-static dir when done

It might not be what you want, but it works well.

Regards,
