COMMANDs for a custom target are not CMake commands.  They are
commands you could run on a command line.  You can't use FILE, you
have to use a system-specific "mkdir" or some such.  You could write a
CMake script with FILE in it, and then invoke the CMake script with
"cmake -P", if you want something guaranteed to be portable.

Come to think of it, "cmake -E mkdir mydirectoryname" is supposed to
have been added, according to bug #3776.  But it isn't in CMake 2.4.6
on Windows.  So, I'm reopening the bug.
