Nice, just some comments.
The variable names should probably be all-uppercase and prefixed with some common prefix.
As it is now you will get complaints from users once they start to change some of these basedirs, since changes their don't propagate to the "inherited" install directories. In KDE in FindKDE4Internal.cmake we did some special handling to do this better (_set_fancy).
Are all those directories required, like "oldincludedir" ?

Bye
Alex
