Sounds as if that is a Windows program, not a Cygwin or Linux program.

If your gcc is a Windows gcc then it wants a Windows path.

This goes along with my theory.

You can fix the Makefile to pass Windows paths.  The cygpath tool and make's
$(shell ...) command might be useful.

But I also wonder if maybe the mingw environment is more suited to this work,
or finding a Windows version of make.

Perhaps there are others here who can clarify or add to this ...   EM
