[question] C++26 and CMAKE_CXX_STANDARD_LATEST #17192

Closed rdong8 closed 2 hours ago

rdong8 commented 2 hours ago

What is your question?

In CMake 3.30 there's a new variable called CMAKE_CXX_STANDARD_LATEST that sets the C++ standard to the latest available from the compiler, what is the Conan equivalent of this in the Conan profile? For instance, on the Clang 18 shipped by Fedora 40, this uses C++26, which Conan does not seem to support yet.

Have you read the CONTRIBUTING guide?

Hi @rdong8

Thanks for your question.

C++26 was added to the default settings.yml in https://github.com/conan-io/conan/pull/17092, that means that it will be in next Conan 2.9 release, typically before the end of the month.

Recall that very often, it is possible to edit and add values to the default settings.yml file, or even better, to add them in the settings_user.yml file, not having to wait until the next Conan release.
