[Interest] Best practice to packages on Ubuntu with QtIF

[Nikos Chantziaras]

That doesn't do anything useful. It just uses an absolute path. If you 
move the executable to a different directory, it stops working.

You can verify that by looking at the Makefile. For example, here, this:

   QMAKE_RPATHDIR += ${ORIGIN}

becomes:

   -Wl,-rpath,/home/realnc/projects/myapp/

Which is completely useless.

Do do what you want, you really need to pass the string "$ORIGIN" to the 
linker:

   QMAKE_LFLAGS += -Wl,-rpath,\$\$ORIGIN

This results in:

   -Wl,-rpath,$ORIGIN

in the Makefile.
