The minimum version in practice used to be 0.50.0, however that can be
lowered by removing unneeded kwargs from a couple of functions.
- i18n.gettext() `install_dir` defaults to the localedir option, and
doesn't need to be manually overridden to that location
- configure_file() `install` defaults to true if `install_dir` is set,
and before 0.50 that was also the *only* way to mark it as installed
Removing both these kwargs means that there is more leeway with the minimum
required version.
Python files are installed into `$DESTDIR/lib/lutris`
Scripts in `/bin` have been edited to search **ALL** module inside this dir
Datas are also searched in `</lib/lutris>/../../share/lutris`, this allow weird DESTDIR like `/tmp/lutris` (tested)
Now Lutris assume that libdir is located in `<bindir>/../lib`
This is minimalist right now and should work for everyone
