Eventually I modified the Makefile in the build dir because it works and was
easier.
Yet I am sending this message because I want to know how I could have do what
I wanted to and I also believe that a nicer solution is a one that does not
require modifying the Makefile.
The $$ works.
As for the backslashes, it seems to me more complicated because the makefile
seems to grab it for itself as a continuation signs.
