[Qt-creator] qmake: how to disable error ignoring for make recipe in Makefile?

[Andrzej Telszewski]

Hi,

When I generate Makefile with qmake, the recipe for installing looks 
something like this:

install_target: first FORCE
	@$(CHK_DIR_EXISTS) $(INSTALL_ROOT)/usr/sbin/ || $(MKDIR) 
$(INSTALL_ROOT)/usr/sbin/
	-$(INSTALL_PROGRAM) "$(QMAKE_TARGET)" 
"$(INSTALL_ROOT)/usr/sbin/$(QMAKE_TARGET)"
	-$(STRIP) "$(INSTALL_ROOT)/usr/sbin/$(QMAKE_TARGET)"

Hyphens "-" are added in front of $(INSTALL_PROGRAM) and $(STRIP). These 
"-" allow to ignore recipe errors.

But I would actually like to switch on failing on recipe error.
How can I do it?
That is, what and where I have to specify for the "-" to be removed?
