osgEarth在OSX 10.10上的编译问题

reacil

各位好~
我尝试在rmbp上编译osgEarth2.6，OSG是最新版3.2.1，操作系统是最新的OSX10.10，Qt5.2，Cmake 3.1.0，用GNU编译器进行编译。
我先尝试编译了osg，参考网上的资料和自己的尝试，编译成功，在Qt中新创建的工程，用简单的例子，成功看到了肥牛~
在编译osgEarth的时候遇到问题：

尝试按照stackoverflow上关于编译opencv类似错误修改了链接的-lstdc++，和Qt中qmake.conf里
QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.6

改成

QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.9

错误仍然存在。

想请教各位，有否遇到过类似问题，如何解决？

谢谢
