[Marble-devel] Marble linking against wrong version of Qt

Hi Dennis,

Thanks for that tip. It led me to a solution.

I was intentionally avoiding LD_LIBRARY_PATH. My application builds the 
rpath into my libs. I forgot that I needed to do this for my marble 
build as well.

So I added "-DCMAKE_INSTALL_RPATH=/opt/Qt/4.8.4/lib" to marble's cmake args.
This got the rpath set correctly.

Things are working now!

Thanks!

Josh
