I understand.

Didn't found the MinGW + DirectX headers download. I read at some point
DirectX libs were removed from MinGW so latest releases don't include such
headers anymore.
However I found some other links which contains extracted headers:

https://sourceforge.net/projects/mingwdx/
https://github.com/lifthrasiir/w32api-directx-standalone
http://liballeg.org/download.html

I guess I can try to check following some guidelines like this one :

Ok, I will let you know how it goes.

Cheers,
