<pre>$ mkdir bar
$ touch bar/foo.h
$ echo 'module foo { header "foo.h" }' > bar/module.map
$ echo '@import foo;' > foo.mm
$ clang foo.mm -Xclang -fmodules -I bar -c
<module-includes>:1:9: fatal error: 'bar/foo.h' file not found
#import "bar/foo.h"
^
1 error generated.
$ clang foo.mm -Xclang -fmodules -I $PWD/bar -c

I believe the problem is that we run the module compilation from within the
directory containing the module.map file, but the -I paths are relative to the
directory containing the original source file.</pre>
