I am trying to build GTest on macOS 11.6 by following a recipe here on StackOverflow. It works until the point at which I have to call the make command. It responds with the following output:
/Library/Developer/CommandLineTools/SDKs/MacOSX11.3.sdk/usr/include/c++/v1/cmath:321:9: error: no member named 'signbit' in the global namespace
using ::signbit;
~~^
/Library/Developer/CommandLineTools/SDKs/MacOSX11.3.sdk/usr/include/c++/v1/cmath:322:9: error: no member named 'fpclassify' in the global namespace
using ::fpclassify;
~~^
[several other errors of this type]
The previous output from cmake is:
-- The C compiler identification is AppleClang 12.0.5.12050022

I also tried to set the flags mentioned by runoraca without success. I have read several posts about similar problems and I think this is a libc++ vs. libstdc++ issue but I am not sure.
