How to compile rasterepson filter?

[Gurmeet Singh]

Hi Experts,

I am developing a driver for using CUPS raster filter for dit matrix printer.
I am using rastertoepson filter.
I have to implement some other features in same filter. How i can compile rastertoepson filter like RAW data,junk printing etc.
I have rastertoepson.c file.
While compiling it is giving error like "cups/string-private.h: No such file or directory".
How i can set up so that it will resolve all dependencies? or i have to copy all dependency files in myfilterfolder?

Please help.
Thanks.
