You're going to need a normal copy of Xcode installed to provide the
system headers and libraries; and macOS has been moving away from
putting anything in /usr/include even with the command line tools.
So you probably need to add an extra sysroot argument to your clang
invocation, pointing it at the Xcode installation: -isysroot $(xcrun
--show-sdk-path macosx). Alternatively I believe you can set the
SDKROOT environment variable to that path, if adding CFLAGS is too
tricky. Build systems often detect all this for you (I know CMake
