Copying supporting DLL to DESTDIR

[WilliamU]

Hi, I am trying (in vain) to copy my project's supporting DLLs to the DESTDIR.

I have in my .pro file
@
debug {
DESTDIR = C:/Users/william/Perforce/Build/Executables/x64/$$TARGET/Debug
POST_TARGETDEPS += C:/Users/william/Perforce/Build/Libraries/QT/Debug/Input.dll
POST_TARGETDEPS += C:/Users/william/Perforce/Build/Libraries/QT/Debug/Output.dll
for(dll, POST_TARGETDEPS){QMAKE_POST_LINK = copy "$$dll" "$$DESTDIR/"}
}
@
My executable arrives correctly but I get the following error build
xilink: executing 'link'
copy C:/Users/william/Perforce/Build/Libraries/QT/Debug/Output.dll C:/Users/william/Perforce/Build/Executables/x64/Monitor/Debug/
The syntax of the command is incorrect.

Does anyone have any suggestions.

Hi, 10 years later. How did you solve this?
