Re: [wxVTK] Basic Question. Compiling on Linux and Windows.

[Sander N. <nie...@st...>]

For gtk2 the situation is a bit less troublesome if you make use of  
pkg-config.
For our project I add the output of `pkg-config --cflags gtk+-2.0` to  
the CPPFLAGS together with -I/usr/X11R6/include and add -lgdk-x11-2.0  
as an additional library to link to.
The use of pkg-config saves you the trouble of enumerating all the -I  
paths for gtk2 yourself.

However, this is all without using CMake.

Best regards,
Sander
