Ah, my error. I thought you wanted this in one of your .cdl files.

You probably need to add some cdl somewhere, something like

cdl_option CYGBLD_GLOBAL_CFLAGS_O2 {
           display  "Compile with -02"
           default  0
           no_define
           requires { is_substr(CYGBLD_GLOBAL_CFLAGS, " -O2") }
}

And then in your .ecm file

cdl_option CYGBLD_GLOBAL_CFLAGS_O2 {
    user_value 1
}
