 Normally, if you create a GTK project you include the "usr/include/gtk+" paths. The problem with that is that "/usr/include/gtk" only contains header files, not the .c source code files from the GitHub repo. As such you won't be able to see the "guts" of GTK, which are often very useful and essential for when you're debugging SWT.
 
-If you point your include to the GTK GitHub repo instead, then it might not compile unless you go thourgh the effort to compile the related libs (GLib/pixbuf etc…), which is quite a bit of effort. I.e, it's easier to use the GTK that is build in with your system for compilation.

 The solution (which at least works for me) is to point the compiler to the system "usr/include" path (1*) and point the indexer to the GTK GitHub repository (2*). This way, when you are compiling, all will compile well and when you are writing code you easy quick-lookup to the GTK source code without having to compile all of this business.
