Your solution may work for your specific case, but it isn't something 
that should be applied in the general case.

Did you try to compile back as a library? When it gets compiled as a 
bundle the gui dependencies should be added automatically.

This may again be a problem of the non-flattened structure you are 
using, but this time I am not sure.
