By default install into the CMAKE Prefix.

Add a option to install that file into the qt prefix. I have to emphasize that 
the default of that option has to be "install into the cmake prefix". Those 
qt-streamer guys  failed to get that right.

If that option not set print out a message stating it will not work and if 
they want to have it work they have to use that option but that will probably 
require root right for installation.

With qt 4.8 print out a warning if that option is not set and inform the user 
that he has to set QMAKESPEC correctly if cmake prefix != qt prefix and the 
option is not set and the sermon above.
