Yeah I know, I can give you all the details for this one. For instance:

http://lists.wxwidgets.org/pipermail/wx-dev/2004-September/050814.html

I have been begging since 2004 for just *ONE* hook in the wxWidgets
library, and they have consistently refuse. Basically they are not
happy that I want to access the XWindow pointer on UNIX to open a
window. There point of view if if you are using wx-gtk1 you need to
know that internally you have open a gtk1 window, and if you want to
access anything hidden in gtk1, then YOU need to include all the gtk1
headers, same goes for gtk2...
So the real problem is that that port that most people use on *NIX is
a double indirection on top of X11, and wx people only probivde access
to the first indirection layer.

the thing that really pi*** me off, is that Robert Roebling has made
this hook available in his python-wx library (the python code of wxVTK
is actually cleaner than the c++ library and does not require
importing anything from gtk*).

Actually if you have python-wx installed on your machine you could
call this python function :-P

I cannot simply make a library made of a single class, the overhead is
AFAIK way too high (dll initialization, static linking...). Therefore
I assumed people would just simply integrate the single C++ class
directly into there project. (*)

Suscribe to wx-dev mailing list, and tell them your story...

No that's not a cmake issue, you HAVE TO (last time I checked) include
the gtk header to be able to extract the XWindow pointer from a
GTKWindow pointer.

(*) There is also a nasty problem due to my initial design, the wxVTK
class has multiple inheritance which make it actually difficult to
wrap in a shared/static library...
