[Cmake] gtk-config / pkg-config

[Mathieu Malaterre]

Andy,

That sounds excellent !

Anyway GTK is still a particular package as it can be accessible either 
way though gtk-config or pkg-config. So if you could find a way to hide 
this in FindGTK.cmake this would be very nice.

And one feature I would like to see is in FindwxWindow, so that it 
determine which GTK was used (I don't know if this is possible without 
using your CMakeLists for wxWindow).

BTW, when will FindPKGConfig.cmake be available ?
