Fix compilation on Windows, add install target

Paths on Windows get confused since I use a strange combination of
some 4 different GNU/Linux-like systems on Windows (cygwin, msys2,
msys git, WSL).

Since Windows doesn't support symlinks properly, I can't use GNU Stow
to install my files. So for Windows I copy over all the necessary
files.
