if/else 如果等价于 qmake/pro Qt 文件

Question

我有时不得不这样写qmake pro文件：

QMAKE_EXTRA_TARGETS += activate

macos {
    clear_cache.commands += defaults write io.delille.$$TARGET activated 1;
}

win32 {
    clear_cache.commands += another working command;
}


linux {
    clear_cache.commands += echo unsupported;
}

ios {
    clear_cache.commands += echo unsupported;
}

有没有办法像大多数语言允许的那样以更简单的方式列出所有不受支持的平台 if if/else if 语句？

Answer 1

qmake knowns about if/else: https://doc.qt.io/qt-5/qmake-language.html#scopes

win32:xml {
    message(Building for Windows)
    SOURCES += xmlhandler_win.cpp
} else:xml {
    SOURCES += xmlhandler.cpp
} else {
    message("Unknown configuration")
}
