Bindgen unable to find libraries even though clang can with the same arguments

help

I created wrapper.h as

#define FUSE_USE_VERSION 25
#include <fuse_lowlevel.h>

and tried to generate bindings using the code

let bindings = bindgen::Builder::default()
  .header("src/wrapper.h")
  .clang_arg("-D_FILE_OFFSET_BITS=64")
  .clang_arg("-I/usr/local/include/fuse")  // Path to FUSE headers
  .parse_callbacks(Box::new(bindgen::CargoCallbacks))
  .generate()
  .expect("Unable to generate bindings");

However it is failing with

  --- stderr
  /usr/local/include/fuse/fuse_lowlevel.h:42:12: fatal error: 'DiskArbitration/DiskArbitration.h' file not found
  /usr/local/include/fuse/fuse_lowlevel.h:42:12: note: did not find header 'DiskArbitration.h' in framework 'DiskArbitration' (loaded from '/System/Library/Frameworks')
  thread 'main' panicked at build.rs:15:10:
  Unable to generate bindings: ClangDiagnostic("/usr/local/include/fuse/fuse_lowlevel.h:42:12: fatal error: 'DiskArbitration/DiskArbitration.h' file not found\n")

However when i created the following c file

#define FUSE_USE_VERSION 25
#include <fuse_lowlevel.h>
int main() {}

i was able to compile it using clang wrapper.c -I/usr/local/include/fuse -D_FILE_OFFSET_BITS=64

I don't understand why clang is able to find it here but not through bindings.

As a last resort I tried the following to preprocess it using clang and then generate bindings for it using clang -E -I/usr/local/include/fuse -D_FILE_OFFSET_BITS=64 wrapper.h -o processed.h but the generated binding is a 26000 line mess 1mb in size so I don't think that's practical...
