I have managed to get CMake 3.11.0 to build by hacking the CLang-CXX file to specify -std=c++1y instead of 1z. With 1z the __cplusplus define is set to a 2017 date such that the CMake code presumes the existence of std::size, which isn’t actually defined in the headers I have (presumably because the system gcc is 5.4.0, circa C++14).
Is there a proper way to specify the -std= to use when running the cmake bootstrap or make? > I am attempting to build the latest release of CMake on my ARM-based Ubuntu > system.
