‘XInputGetStateEx’ was not declared in this scope

Hi,

I tried to compile the 64 bit version of your library but ran into this problem after installing libwine-dev libsdl2-dev cmake and build-essential using apt-get on an Ubuntu 17.04:

user@calculator:~/Downloads/koku-xinput-wine-1.2.1$ cmake -DBUILD_M32=OFF .

Any idea what I am missing?

I removed all parts which contain XINPUT_STATE_EX and XInputGetStateEx in your code because it seems these things are no more included in xinput.h

After also installing gcc-multilib and g++-multilib I was finally able to compile but now the linker does not find -lSDL2. How can that be?

After apt-get purge libsdl2-dev and apt-get autoremove I finally was able to apt-get install libsdl2-dev:i386 with its dependencies without problems and the compilation of the 32 bit library was also successful. Now the library works without problems. I still don't know what's the issue with XINPUT_STATE_EX and XInputGetStateEx.
