Subject: Added include_path and dependencies for FreeBSD < 10.0
X-Git-Tag: v3_12~732^2~29
X-Git-Url: http://info.iut-bm.univ-fcomte.fr/pub/gitweb/simgrid.git/commitdiff_plain/8c1171f84bdfac07290430a0462e91350c4553cf

Added include_path and dependencies for FreeBSD < 10.0

- Commit eea4e2cc87b80c35b33f46377187181e57692440 has enabled C++11
  for SimGrid. However, FreeBSD 9.1 does not have a compiler that
  supports this. Here's a nasty workaround, making the bold assumption
  that libc++ is installed (by default, it's not) and where we can
  find it.

- With this hack, FreeBSD CI should work again :)
