[CMake] fixup bundle vs Qy 5.5.1 and rpaths

[clinton at elemtech.com]

It appears you need to add the directory(ies) in the Qt installation containing the Qt libraries to your DIRS. 

set( DIRS 
${APP}/Contents/plugins/platforms 
${QT_BINARY_DIR} 
${QT_LIBRARY_DIR} 
) 

I think it should have been that way, even with Qt 5.3.
