Qt中qmake的INSTALLS变量将编译文件拷到运行目录

找了好久都没有找到很清晰的说明。特地记录一下。
下是qml-material.git项目的工程配置文件内容：

TEMPLATE = lib
TARGET = material

CONFIG += c++11
QT += qml quick

android {
    QT += androidextras svg xml
}

HEADERS += plugin.h \
           core/device.h \
           core/units.h

SOURCES += plugin.cpp \
           core/device.cpp \
           core/units.cpp

RESOURCES += ../icons/core_icons.qrc

target.path = $$[QT_INSTALL_QML]/Material

material.files +=  \
                    components/* \
                    controls/* \
                    core/* \
                    popups/* \
                    window/*
material.path = $$[QT_INSTALL_QML]/Material

extras.files += extras/*
extras.path = $$[QT_INSTALL_QML]/Material/Extras

listitems.files += listitems/*
listitems.path = $$[QT_INSTALL_QML]/Material/ListItems

styles.files += styles/*
styles.path = $$[QT_INSTALL_QML]/QtQuick/Controls/Styles/Material

#qmldir.target = $$OUT_PWD/out/qmldir
#qmldir.commands = mkdir -p $$OUT_PWD/out;
#qmldir.commands += sed \"s/$$LITERAL_HASH plugin material/plugin material/\" $$PWD/qmldir > $$qmldir.target
#qmldir.depends = $$PWD/qmldir
qmldir.path = $$[QT_INSTALL_QML]/Material
qmldir.files = $$PWD/qmldir
qmldir.CONFIG += no_check_exist

INSTALLS += target material extras listitems styles qmldir

OTHER_FILES += $$material.files $$extras.files $$listitems.files $$styles.files

配置文件的意图很明确：就是将material、extras、styles、qmldir这些变量对应的文件拷贝到Qt的qml插件目录下的Material文件夹下。

但是 INSTALLS 变量，在按下Build按钮之后并没有执行拷贝操作

需要在Qt Creator中配置一下该项目：这样子设置以后，按下build之后，就会在make完之后，继续执行INSTALLS的拷贝操作
