-mllvm and -bitcode_bundle (Xcode setting ENABLE_BITCODE=YES) cannot be used together

Hi, I am getting the following error while building my project:

-mllvm and -bitcode_bundle (Xcode setting ENABLE_BITCODE=YES) cannot be used together

Even though I do not set (manually) the -mllvm option anywhere in my CMakeLists.txt files. The only place where I see the -mllvm option being passed is in the CMakeConfigureLog.yaml log file.

Namely in the line (-mllvm -enable-linkonceodr-outlining):

Is there some way to get rid of using the -mllvm option if I want to pass -fembed-bitcode? Or any other ways to solve this problem?
