Qmake Command to copy directory and files

问题:

I want to copy the contents in directory "temp" to "dd"

BINARY_DESTINATION_PATH = $$PWD$$SEPARATOR/dd/
RESOURCE_SOURCE_PATH = $$PWD$$SEPARATOR/temp

EXPORTED_DESTINATION_PATH = $${BINARY_DESTINATION_PATH}
EXPORTED_DESTINATION_PATH ~= s,/,\\,g

EXPORTED_SOURCE_PATH = $${RESOURCE_SOURCE_PATH}
EXPORTED_SOURCE_PATH ~= s,/,\\,g

QT += core
QT -= gui

CONFIG += c++11

TARGET = sample
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app

SOURCES += main.cpp

win32 {
QMAKE_POST_LINK += $$quote(cmd /c xcopy /S /I /Y $${EXPORTED_HEADERS}\\copy_to_output $${EXPORTED_HEADERS_WIN})
}

but this is not adding the files into dd and showing error on build. Error i son line "QMAKE_POST_LINK"

回答1:

quote(string)

Converts a whole string into a single entity and returns the result. This is just a fancy way of enclosing the string into double quotes.

What you're probably looking for is system(command).
