Roslyn compiled library doesn' recognize the path of reference library

Hello All,

I'm working on a Roslyn compiler project where i use 2 roslyn compiled dll's in another roslyn compilation. The DLL is properly created 2nd time too, but when i create an instance for the classes in the DLL, it complains that it cannot find the path of the 1st 2 DLL's as references and throws FileNotFindException while. Anythought on it? BTW the compilation is happening in one project but the instance creation is another project but in same solution with Project refernces added.

Thank you.
