Building Corrade with -std=c++20 causes errors inside MinGW <numbers> header about corrade HOT 3 CLOSED

Hm, I don't feel like adding workarounds for broken compilers, sorry 😅

What you could do is to not build Corrade with -std=c++20, it only makes the build slower for no reason. Then it won't / shouldn't include the C++20-specific <numbers> header and thus should circumvent this error.

You're right.

Using

target_compile_features(${PROJECT_NAME} PUBLIC cxx_std_20)

instead of

SET(CMAKE_CXX_STANDARD 20)

does get past this specific problem.

I'm fine if you want to close this issue.

Thank you for the confirmation 👍

I edited the issue title to make it easier to find when someone else hits the same issue, but I'm going to close it, yes -- this is a STL bug, not something a library should be fixing from outside.
