But you have to be very careful when creating this PATH. Order is important or you will likely catch the wrong Qt release libraries. After all, even CMake ships Qt dlls in its installation directory. And other tools that are user during build might also do.

Additionally, CMake is not able to set this up automatically in VS.

Also, when the Qt dlls can be found so easily, why doesn't FindQt4 do it?
