Not everything supports response files (it's usually compilers and MS
tools). One thing we could do is detect when an add_custom_command or
add_custom_target might run foul of command line length limits and warn
for it. I don't know what else we could do without teaching CMake about
every command's semantics. I suppose we could add response file wrappers
around all long command lines, but command line parsing on Windows can
be 100% custom, so there might need problems there :/ .
