Is this what you are looking for https://stackoverflow.com/a/36438513?
Another method here .
Alternatively you can use copy http://doc.qt.io/qt-5/qfile.html#copy-1 if file does not exists else you need to check if exists and remove them and then copy.

The above links are usefull and correct, I'll add a small function, inside the *.pro file, I'll use to copy files

DESTDIR     = deployment

...

# copies the given files to the destination directory
defineTest(copyToDestDir) {
    files = $$1
    dir = $$2
    # replace slashes in destination path for Windows
    win32:dir ~= s,/,\\,g

    for(file, files) {
        # replace slashes in source path for Windows
        win32:file ~= s,/,\\,g

        QMAKE_POST_LINK += $$QMAKE_COPY_DIR $$shell_quote($$file) $$shell_quote($$dir) $$escape_expand(\\n\\t)
    }

    export(QMAKE_POST_LINK)
}

#Use
copyToDestDir($$PWD/translations, deployment/translations)

I had try it in my windows qt project,but it not work for me and I don't no why,in my project there is a subDirectory which named 'Files' and a 1.txt file in it, here is the .pro file :

ROOT_DIRECTORY = $$PWD
LIB_DIRECTORY = $${ROOT_DIRECTORY}/lib
BUILD_DIRECTORY = $${ROOT_DIRECTORY}/build
TESTS_DIRECTORY = $${BUILD_DIRECTORY}/tests
EXAMPLES_DIRECTORY = $${BUILD_DIRECTORY}/examples
EXEC_DIRECTORY = $${BUILD_DIRECTORY}

#$${LIB_DIRECTORY}
DESTDIR = $${EXEC_DIRECTORY}
OBJECTS_DIR = $${BUILD_DIRECTORY}
MOC_DIR = $${BUILD_DIRECTORY}
RCC_DIR = $${BUILD_DIRECTORY}

copies the given files to the destination directory

defineTest(copyToDestDir) {
files = $$1
dir = $$2
# replace slashes in destination path for Windows
win32:dir ~= s,/,\,g

for(file, files) {
    # replace slashes in source path for Windows
    win32:file ~= s,/,\\,g

    QMAKE_POST_LINK += $$QMAKE_COPY_DIR $$shell_quote($$file) $$shell_quote($$dir) $$escape_expand(\\n\\t)
}

export(QMAKE_POST_LINK)

}

#Use
copyToDestDir($$PWD/Files/, $$DESTDIR/)

@Princein said in how copy the file which in my project directory to the .exe file directory in windows:

copyToDestDir($$PWD/Files/, $$DESTDIR/)

try it with

copyToDestDir($$PWD/Files, $$DESTDIR)

fixed my post DESTDIR needs the $$ prefix, but if you omit the trailing / it should work. I just tested it.

I had tried, but I still not work, and then I changed to 'copyToDestDir($$PWD/Files/, C:\Users\Administrator\Desktop)' ,it still not work too!

copyToDestDir($$PWD/Files, C:\Users\Administrator\Desktop)

I create a two directory in desktop filecopy1 and filecopy2, in the filecopy1 directory, there is a 1.txt file and 2.jpg file,so I change the .pro to

copyToDestDir( C:\Users\Administrator\Desktop\filecopy1,C:\Users\Administrator\Desktop\filecopy2)

it still not work

@Princein
use forward slashes or double backwards, the expression doesn't cover simple backwards slashes.

@J.Hilk

#copyToDestDir( C:/Users/Administrator/Desktop/filecopy1,C:/Users/Administrator/Desktop/filecopy2)

copyToDestDir( C:\Users\Administrator\Desktop\filecopy1,C:\Users\Administrator\Desktop\filecopy2)

I had tried the '/' and '\' , but now work too, it seem this way has problem, I find a good way, it work for me, and can work on both windows and macos:

copydata.commands = $(COPY_DIR) C:\Users\Administrator\Desktop\filecopy1 C:\Users\Administrator\Desktop\filecopy2
first.depends = $(first) copydata
export(first.depends)
export(copydata.commands)
QMAKE_EXTRA_TARGETS += first copydata

replace slashes in destination path for Windows

win32:dir ~= s,/,,g

Could it be because you need two backslashes before the 'g' ?
Edit:
and dont forget to re-run qmake whenever changing the file.
