此处有大坑，如果使用最新版 cmake ,3.9.3, 运行cmake报错
The C compiler "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang" is not able to compile a simple test program.

步骤
- 代码
1.1 Download OSG trunk
cd /Users/wangmiao/projects/osgearth-build/osg-ios/
git clone https://github.com/openscenegraph/OpenSceneGraph.git
1.2 修改CMakeList.tx
Edit CMakeList.txt to point to your version of iOS SDK:
Check
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs
Open CMakeList.txt and change to your SDK version:(SET (IPHONE_SDKVER "5.1" CACHE STRING "IOS SDK-Version")

换台电脑
1.创建cateye user,
- copy 对应文件，修改 owner:
sudo chown -R cateye:staff ./*
