跑步cmake -DCMAKE_TOOLCHAIN_FILE=ceres-solver/cmake/iOS.cmake -DCMAKE_CXX_FLAGS="-stdlib=libc++" -DEIGEN_INCLUDE_DIR=/usr/local/Cellar/eigen -DIOS_PLATFORM=OS ceres-solver

给了我这些错误

即使我将 CXX11 设置为 ON，我也会得到同样的错误。我应该怎么办？

假设我得到这个工作，我只是跑来make install获取libceres.a文件吗？

很多帮助表示赞赏。

这不是 C++11 错误，请注意错误

CMake 错误：生成器：make 执行失败。制作命令是：“CMAKE_MAKE_PROGRAM”“cmTC_3feba/fast”

CMake 试图通过编译几个简短的程序片段来确定各种 c++11 功能的存在，但由于一些与 Make 相关的问题（您是否安装了 make？Xcore 命令行工具？）而无法这样做，并且它结束了得出结论，c++11 不可用。

这里要解决的问题是查看系统上的 Make 发生了什么。
