This is really bad! You have to use stdc++ for every project that uses PCL in Mac and the same for the dependencies. I think it would be better to disable CUDA if using libc++ and enable it when using libstdc++. |

I agree - if one wants to compile without CUDA this is ugly. Maybe an additional CUDA-test in the if-clause for adding libstdc++ if CUDA is enabled and not touch anything otherwise? |

The reason why the libstdc++ flag is ugly to specify manually from command line is that the necessary flags on line 151 are only added if cxxflags is empty, so they must in that case also be included by anyone building on Mac with CUDA |

In OSX 10.9, libc++ is now the default standard library on Mac. libc++ is not compatible with CUDA so pcl fails to build unless the previous stdlib is specified explicitly
