It is about installing the development libraries themselves. I am doing a test installation using the guide here [http://wiki.geany.org/howtos/win32/msys2](http://forum.nim-lang.org///wiki.geany.org/howtos/win32/msys2) to see if I can get an GTK 3 project working and if I succeeds I will see if I can connect Nim to the downloaded files.
Which directory are your GNOME development libraries themselves installed, ie those with the 'dev' or 'devel' suffix?
