How to add a dependency to a windres-ressource (rc) file w/ mingw

[franku]

The following works with (and most likely with former versions as well):
QMake version 3.0
Using Qt version 5.1.1

#call the ressource compiler
win32:mkver_rc.target = version_res.o
win32:mkver_rc.depends = version.h
win32:mkver_rc.commands = windres -i version.rc -o version_res.o --include-dir=. -DVERSION_H_INTERN $(DEFINES)
win32:QMAKE_EXTRA_TARGETS += mkver_rc
win32:PRE_TARGETDEPS += version_res.o
 
LIBS += version_res.o

#call the ressource compiler
win32:mkver_rc.target = version_res.o
win32:mkver_rc.depends = version.h
win32:mkver_rc.commands = windres -i version.rc -o version_res.o --include-dir=. -DVERSION_H_INTERN $(DEFINES)
win32:QMAKE_EXTRA_TARGETS += mkver_rc
win32:PRE_TARGETDEPS += version_res.o

LIBS += version_res.o
