Building project with clang-cl in VS2019

I'm trying to build a project with clang-cl in Visual Studio 2019 checking C++17 option in the project's properties. And I get the warning:

constexpr if is a C++17 extension [-Wc++17-extensions]

I suppose that it should appear only for code that is not compiled as C++17. So why do I get this? Is the code compiled as C++17?

One possibility is that you have a different Standard selected for your project and an individual source file in that project. Try checking the "Language" option in the property sheet for the 'offending' source file(s) – make sure it is also set to use the C++17 Standard.
