Using XWiimote deprecated function

[jgvictores]

To solve #134, 6735632 was introduced.

1. If we continue with old distros (see Try hc-driver-4.9 on TEO teo-main#26 and related), see if we can catch xwii version via preprocessor and #ifdefaccordingly.
2. If we move on to newer distros on all systems, move on to newer function again.

I could either parse the version string from /usr/lib/x86_64-linux-gnu/pkgconfig/libxwiimote.pc (not the best idea if the location/format of this file differs from one architecture/OS to another) or start playing with try_run().

Edit: or improve FindXWiimote.cmake so that a XWIIMOTE_VERSION is set, then either restrict building this component from v2 onwards only or support v0.3 (with the old xwii_iface_poll) via preprocessor definition.

In addition to priority: low, added blocked by roboticslab-uc3m/teo-main#26 label. BTW, could add interesting label too. 😄

I actually gave a try to the pkg-config solution mixed with find modules and seems promising, expect updates soon.

This is not a big deal: .pc files should land in some standard location and CMake takes care of the rest with pkg_check_modules().

Should be fine at 0eb18f3, closing as done. I'll write down this page here as it explains quite a few useful things about find modules:

Cool commit!

Also added the ref to the cmake wiki at https://github.com/asrob-uc3m/tutoriales/blob/master/software/programming/cmake.md

And how FindXWiimote.cmake looks now: link.

Thanks! Updated here!
