My condolences :p.

Usually, problems like this are caused by improper quoting. First, try
the VERBATIM flag to add_custom_command.

You can inspect the command line CMake generates for your custom command
by doing make VERBOSE=1. Hopefully this will give you a clue as to what
is getting mangled.

Finally, arguments to macros occasionally do funny things since they
aren't "real" variables, but that's probably not the problem here.
