Object file was built for newer OSX version than being linked

I'm getting this error for C++ library I'm using. It uses GNU Automake for building. Which flag(s) I should supply for the makecommand to lower the target build platform to avoid seeing this warning in Xcode project where I'm trying to link against the library?
我正在使用的 C++ 库出现此错误。它使用 GNU Automake 进行构建。我应该为make命令提供哪个标志来降低目标构建平台以避免在我尝试链接库的 Xcode 项目中看到此警告？

You need to set the compiler flag -mmacosx-version-minto the version number of the SDK you want to build against. I don't use automake, but in cmakeyou'd set the variable CMAKE_OSX_DEPLOYMENT_TARGET, and in qmakeyou'd set the variable QMAKE_MACOSX_DEPLOYMENT_TARGET.
您需要将编译器标志设置为-mmacosx-version-min要针对其构建的 SDK 的版本号。我不使用automake，但在cmake你设置变量时CMAKE_OSX_DEPLOYMENT_TARGET，qmake你会设置变量QMAKE_MACOSX_DEPLOYMENT_TARGET。

As cbrnr answered, you have to use -mmacosx-version-min compiler flag. To pass compiler flag through make, you can use CXXFLAGS environment variable:
正如 cbrnr 回答的那样，您必须使用 -mmacosx-version-min 编译器标志。要通过 make 传递编译器标志，您可以使用 CXXFLAGS 环境变量：
make CXXFLAGS="-mmacosx-version-min=10.10" <target or other make params>
