make QMAKE_CLEAN delete whole directories?

[Teerayoot]

I think you can edit qmake.conf
in mkspecs folder

some example

QMAKE_COPY              = copy /y
QMAKE_COPY_DIR          = xcopy /s /q /y /i
QMAKE_MOVE              = move
QMAKE_DEL_FILE          = del
QMAKE_DEL_DIR           = rmdir
QMAKE_CHK_DIR_EXISTS    = if not exist
QMAKE_MKDIR             = mkdir

QMAKE_COPY              = copy /y
QMAKE_COPY_DIR          = xcopy /s /q /y /i
QMAKE_MOVE              = move
QMAKE_DEL_FILE          = del
QMAKE_DEL_DIR           = rmdir
QMAKE_CHK_DIR_EXISTS    = if not exist
QMAKE_MKDIR             = mkdir

To copy to clipboard, switch view to plain text mode

well, but that's basically overriding the official qmake setup...
