Msys64\usr\include not in the include path

Hi,
Using QtCreator on windows 7, I create a new project including ofxOsc.
The compilation fail:

of_v0.9.8_msys2_release\addons\ofxOsc\libs\oscpack\src\ip\posix\UdpSocket.cpp:43: erreur : netdb.h: No such file or directory
#include <netdb.h>

I find this file here C:\msys64\usr\include\netdb.h
But this folder is not in the included paths, as I can see in the compiler call:

Does anybody know what I have to modify ?
Thank you.

I did a fresh install of QtCreator and msys2 but my problem persist. I’m wondering: should I open a new issue in github for this problem ? What do you think ?

For now I’m stuck and I can’t build anymore. I can’t even use make because I can’t figure how to use the project generator (No project generator for of_v0.9.x_msys2_release?). I like open source. My best choice would be to code with emacs, which I discovered this year, but now I’m considering to use VS for OF :disappointed:
