dub - load shared library (so) in example

[MGW via Digitalmars-d-learn]

I make a packet for dub in Linux. In a packet there is libQt.so 
which is loaded by an example of D. Usually I execute 
LD_LIBRARY_PATH='pwd'; export LD_LIBRARY_PATH, but now it is 
necessary to make it in dub. How to make it?
