It's possible to add install targets in scons but upstream is not using any of
those.

The easiest is to look on the prefix of the libs. And we always have libtool's
install mode. I already sort the shlibs into a subdir of lib using rpath
(./lib/usr/lib). Here we already have our prefix but it could be done more
elegant.

Baptiste can you tell us your opinion.
