Unfortunately it doesn't work.
The inherited value is not passed on to the compiler.

In my code I have

    #if FOO
        printf("FOO == 1\n");
    #else
        printf("FOO == 0\n);
    #endif

and a similar snippert for BAR.
I have FOO=1 in the Preprocessor Macros in the project build settings.
The command line is
xcodebuild GCC_PREPROCESSOR_DEFINITIONS="$(value) BAR=1"

Only -DBAR=1 is passed on to the compiler. Hence when I run the code,
the output is

FOO == 0
BAR == 1
