Then the 100 points question is: If all of them point to a directory with a qt installed (three different versions). Which one wins? a) CMAKE_PREFIX_PATH b) PATH c) QTDIR I remember more than one newbie losing his grip over not beeing able to convince cmake to pickup the right one.

But there are some executables build and the run during a build that need to pickup the right libs too. I am not sure all of them are doing it right or if there is a right way to do it.
