I dont think you understand the ploblem.  The makefiles already do that.  The 
problem it that the library must be able to find it's DTD files at runtime.  
So during compilation the search path must find it's way in the source code.  
I've put all the usual paths in the code, but if someone install's libofx in 
an eusoteric place it won't find the files.

Maybe I could passs it from the makefiles using a macro in the code?
