@Nekto89 Hello! Conan avoids touching the compiler configuration provided by upstream. The error you see is related to the upstream project, not the package. I would suggest ask the the upstream about that warning.

Doing a quick search, I found is a "bug" in LLVM: https://bugs.llvm.org/show_bug.cgi?id=24979
