I'm trying to compile additional files with -Xcompile-source, but getting this error on macos:

This usually means that your header search paths are not configured properly.           The header search paths should contain the C++ Standard Library headers before           any C Standard Library, and you are probably using compiler flags that make that           not be the case.

I tried adding the following the the relevant cinterops but it also didn't work:

if (target.name.startsWith("macos")) {
                        extraOpts("-Xsource-compiler-option", "-isystem~/.konan/dependencies/apple-llvm-20200714-macos-${if (System.getProperty("os.arch") in arrayOf("amd64", "x86_64")) "x64" else "aarch64"}-essentials/lib/clang/11.1.0/include")
                        extraOpts("-Xsource-compiler-option", "-isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk")
                    }
