Innapropriate ilink32 error

I have coded a Windows 32 VCL application using Embarcadero C++ builder  EX10.1 Berlin and using a winsoft TOBR barcode recognition component.
The application worked.
I now wish to no longer use the Winsoft component in the application so I removed it from the project entirely,including the library and the obr.hpp header file.
The project now compiles but I get a linker error that the file OBR.OBJ cannot be found when the project no loger uses the component as far as I can see.
Where is the linker getting the reference to OBR.OBJ from or how can I get rid of the error ?

The ilink32 command line is as follows :
