Sorry about that, but I did warned people :)

Just like debian, cmake inspection should work for that case. Now the
question, is :

1. On win32, everything is found: rpc.h & rpcrt4 are always there
2. On MacOSX, it seems that uuid.h get installed by default (ref:
Mathieu Coursolle)
3. On *NIX system, we will have two modes:
  3.1 one where the old behavior is still used (handcrafted
pseudo-uuid generation) or
  3.2 if uuid is found (header+libuuid.so symlink) then use this lib instead.

Technically with cmake 2.6 I could be doing solution 3.2 even if the
*-dev package is not installed. So this make the library behaves with
a minor difference, on one specific target.
