how to import file from another path in dub ?

[Flaze07]

I have a dub project, and I put the importPath to the path of the 
file I want to import and the source file to the source folder, 
and it appears that I have succeeded at importing the module, but 
there's one problem, it appears like I need to define some sort 
of thing, because the error says " Error 42: Symbol Undefined 
__D9animation12__ModuleInfoZ" ( I am using coedit ), do I need to 
compile the file into .lib ?
