[ITK-users] ITK 4.8.1, OS X 10.10 and C++11 Support

[Michael Jackson]

The issue is that I am probably missing something when configuring ITK. Looking in my CMake configure logs I have this message:

Run Build Command:"/usr/local/bin/ninja" "cmTC_2927f"
[1/2] Building CXX object CMakeFiles/cmTC_2927f.dir/CheckIncludeFile.cxx.o

ninja: build stopped: subcommand failed.

If you take that same command line and file to compile but simply add "-std=c++11 -stdlib=libc++” to the command line then the compile succeeds. So this is clearly a “user error”. How do I ensure that when CMake is running all of its detection tests that those flags get added? Otherwise the tests are not really valid for the way I am going to compile the codes. I figured by creating an initial CMakeCache.txt file that those flags would get added to every “test” but I guess that is not the way to accomplish that task.
