I was thinking about it again, and am now unsure about upstreaming the
current solution: it might solve most of the problems, as 99% of the
users install their ports to the default location (/usr/local), but if,
say, X11 and Soprano are installed into /opt/custom-prefix, the original
problem will show up again. The same would also happen on Linux, it just
happens that packages are installed into /usr most of the time.

I'm now thinking of simply removing this commit and relying on people
not having a local and a global installation of Soprano (or of
$SOFTWARE, for that matter), or adding /usr/local/include to
IMPLICIT_INCLUDE_DIRECTORIES in FreeBSD.cmake. Neither solution looks
very good, though.

Opinions?
