A close follow up.

I finally figured out what didn't work.

The setting of the QTIFWDIR variable is not saved to the 
CPack*Config.cmake files. But the CMAKE_WIX_ROOT variable is. Those 
variables seem to be evaluated at runtime by CPack. Therefore the WIX 
build run successfully but the IFW build complained about a the path. 
Adding the variable with its current setting made everything run as 
expected.
