从cmake 3.8版本开始,cmake可识别的编译特性增加了代表C++标准的特性名:cxx_std_98,cxx_std_11,cxx_std_14,cxx_std_17 最新的cmake 3.23版本还增加了cxx_std_20,cxx_std_23《High level meta features indicating C++ standard support》 有这个CMAKE_CXX_COMPILE_FEATURES变量,判断编译支持的标准就变得很简单...

I'd be very grateful to any help pointing out what I'm doing wrong. Here's the setup that I would have thought would work: cmake -G "Unix Makefiles" ^ -DCMAKE_INSTALL_PREFIX=%INSTALL_TARGET% ^ -DCMAKE_CXX_STANDARD=17 ^ -DCMAKE_C_COMPILER="%CROSS_CC%" ^ -DCMAKE_CXX_COMPI...
target_compile_features(Foo PUBLIC cxx_std_20) And with this you can and should remove the old set(CMAKE_CXX_STANDARD*). However the new version has an issue if you also want to disable compiler extensions with set(CMAKE_CXX_EXTENSIONS OFF). Its not possible with the new syntax as f...
It would be very convenient if the cmake_paths could also override the CMAKE_CXX_STANDARD_LIBRARIES to ensure that the STL is the same as for project, and for packages. It could generate an additional CMake code for setting the proper ST...
