My libdwarf.h and dwarf.h are available through <libdwarf.h> and
<dwarf.h>, these are in /usr/include

But even by fixing the include path in the makefile and probe-finder.h,
I get the following build error:

util/probe-finder.c: In function ‘die_get_entrypc’:
util/probe-finder.c:222: erreur: ‘Dwarf_Ranges’ undeclared (first use in this function)

I remember we talked about that before, but I don't remember well why it happened.
This is because of a libdwarf version or something, right?

Which one should I pick? Mine is:

    libdwarf.h
