Comment (by rrahn):

 Right, these first two path changes were not intentionally.
 For the pkgconfig, I wasn't actually sure but thanks for pointing that
 out. It seems that `${prefix}/share/pkgconfig` is also a valid path.
 For cmake the given path is in the standard search path according to the
 `find_package` documentation. But if you prefer to install it into `lib` I
 can do that.
