[SOLVED] How can I override the language standard to be -std=c++17 (not std=gnu++17) for GCC using CMake?

Issue

I use these CMake settings:

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED True)
set(CMAKE_VERBOSE_MAKEFILE on)

id='dv3'>

Solution

set(CMAKE_CXX_EXTENSIONS OFF)

or

cmake -DCMAKE_CXX_EXTENSIONS=OFF <...>

It sets CXX_EXTENSIONS property.

This property specifies whether compiler specific extensions should be used. For some compilers, this results in adding a flag such as -std=gnu++11 instead of -std=c++11 to the compile line. This property is ON by default. The basic C++ standard level is controlled by the CXX_STANDARD target property.
