[waffle] [PATCH 3/4] cmake: Add the installed package files to the registry on windows

[Dylan Baker]

This adds the locations of the package files to the registry on windows,
which should allow them to be auto detected by cmake on windows when
linking against waffle in other projects.

This patch is completely untested (I don't have access to a windows
development machine, nor do I want to maintain one), I've sent this as a
courtesy to windows users, and hopefully it can point an interested part
in the correct direction.

Note that this installs into the local machine registry, and there is
also the option of using local user registry instead, and that can be
done by changing waffle to use export(), though I'm not exactly sure how
that works either
