Mixed linking of libc++ and libstdc++ on Mac when setting target to 10.8 on 10.10 machine
I have a 10.10 machine and I set the build target to 10.8 in the superbuild. In this scenario, all the libraries in cmb/smtk and their dependencies will link against libstdc++, except boost libraries, which will link against libc++, and the mixed linking of libstdc++ and libc++ causes crash when launching ModelBuilder. Setting target to 10.9 and 10.10 does not have this problem.
