You'll need to give more precise details.

What directory is make in when it executes?  Where are the idl files
(that was in your email, but please restate it in a complete context)?
Where do you want the output files generated?  What are the
prerequisites used to find the .idl files--presumably foo.o depends on
foo.cc and foo.h for example: where are the .o files?  What exactly does
the target/prerequisite line look like (what pathnames are used, etc.)?

If you could provide a complete, but small, makefile that showed the
problem, substituting "echo" or "cp" for the IDL_COMMAND, that would be
very helpful.
