Use "${CMAKE_CFG_INTDIR}" in the context of add_custom_command OUTPUT, not $<CONFIG>.
You may also use that in the COMMAND arguments. See documentation here: http://www.cmake.org/cmake/help/v3.0/variable/CMAKE_CFG_INTDIR.html The $<> generator expressions are relatively new, and do not work in all contexts that you might expect yet. CMAKE_CFG_INTDIR has been around for quite some time, though, and works very well with custom commands.
