qmake的配置功能(Configuration Features)

Configuration Featuresqmake can be set up with extra configuration features that are specified in feature (.prf) files. These extra features often provide support for custom tools that are used during the build process. To add a feature to the build process, append the feature name (the stem of the feature filename) to the CONFIG variable.For example, qmake can configure the build process to take advantage of external libraries that are supported by pkg-config, such as the D-Bus and ogg libraries, with the following lines:

For more information about adding features, see Adding New Configuration Features.qmake可以设置被(.prf)文件指定的外部配置功能。
这些外部功能常常在构建过程中给自定义的工具提供支持。
增加一个功能到构建过程，追加功能名（不带后缀的功能文件名）到CONFIG变量。
例如，qmake可以利用 pkg-config 支持的外部库配置构建过程，像D-Bus和ogg库，使用下面的2行：
CONFIG += link_pkgconfig
PKGCONFIG += ogg dbus-1
