how to install Qt 4.8.4 with exsist Qt 5.1.1

I have installed version of Qt 5.1.1, and I want to install Qt 4.8.5
because I need to use NCreport library and this library is compatible only
with Qt 4.8.5 and Qt 5.1.1 MVS.
How I can install Qt 4.8.5 with exist Qt 5.1.1 to be able to use NCRrepot
library?
