How to make xmake build all targets except for a specific target?

[Oyyko]

I want to ask xmake to build every targets except for one specific target. How to implement this? I konw --all can ask xmake to build all targets.

[star-hengxing]

option("for_A")
    set_default(false)
    set_showmenu(true)
option_end()

target("A")
    set_enabled(has_config("for_A"))

or

target("A")
    set_group("group1")

target("B")
    set_group("group2")

target("C")
    set_group("group2")

-- xmake build -g group2
