[scribus] Compiling Scribus for Qt5

[Rolf-Werner Eilert]

This is purely "just for fun", so just tell me if I try something 
impossible.

As I was interested in Qt5 libraries for my somewhat older Linux, I 
downloaded the sources and browsed the documentation. The first thing I 
found was how to compile the source statically into $HOME/qt5.

Having done so, I wonder how to compile and link the Scribus 1.5 source 
to this version.

Compiling Qt5,
- "make" ran through flawlessly
- I have not yet issued "make install" because it wasn't mentioned - is 
it necessary, anyway?

If I am not completely on the wrong path up to here, what would be the 
necessary options to give for linking the Scribus sources to my personal 
qt5?

Thanks for your advice!
