Add them as `-isystem` into the [shell script wrapper](Install#shell-script-wrapper). For example:

With clang < 8, `"-isystem", "/Library/Developer/CommandLineTools/usr/include/c++/v1"` is also needed (https://github.com/MaskRay/ccls/issues/191#issuecomment-453809905) To build from source:

With most recent MacOSs(e.g. Catalina 10.15.2), one more clang.extraArgs is needed to make ccls work properly (https://github.com/MaskRay/ccls/issues/512#issuecomment-545575369) brew info llvm
