[CMake] compiling idl files

[Jon W]

Adding the idl files as source seems to work to a certain point, but
I'm missing some syntax to have this work in reality.  I'm not sure
how to write this syntax to then compile the .c and .h files that are
generated by midl.  Maybe another cmakelist.txt file?

Thank you for the macro.  Right now I'll try this with midl to compile
the idl files.

If anybody else has examples, please let me know.
