[CMake] XCode, CMAKE_CFG_INTDIR, and add_custom_command

[David Cole]

It should be fairly easy to add a 2nd custom command that creates the
directory and writes out a stamp file and then make your 1st custom command
depend on the stamp file.
I would go with that approach and put stuff where you want it rather than
trying to figure out where all the varied generators put things...
